If evolution is real then why do humans have such poor sight, sense of smell, and hearing?

Because our brain is the only brain that has advanced. Can you think of a single creature that has developed higher consciousness over 50 million years? No, they were all selected for senses and physical power.

Get this: We didn't need incredible sight, hearing or smell to hunt in groups, we needed communication. We do well at communication. If there is a better species than us in terms of communication, please tell me.

Thats what I'm saying. Why don't you see our brains as being more physically advanced?

You (if you're this user ) said that all animals except for humans improved physically and youre attributing a physical advancement as superior, then why aren't you looking at our brains and realizing that we ARE more physically advanced than other creatures.

A higher consciousness could be argued to be the result of a larger brain in early hominims, and a higher consciousness complemented some of our better physical adaptations. We developed thumbs, like the rest of the apes, and our hands have better dexterity compared to said apes. We also developed an upright posture that allowed us to become bipedal while freeing up our other limbs, and there's numerous endurance running hypotheses that claim humans to be the champions of long distance running, which allowed us to hunt earlier prey by exhausting them.

Whatever we lack physically, we make up mentally, just like other animals compensate their lack of intelligence (compared to humans) physically.

Exactly. Nothing can think like us, so nothing can threaten us but ourselves. We have adapted to create offspring that think better than us.

You assume that evolution is some sort of upward driving force, it isn't. Natural selection (which isn't the only factor driving evolution) does not necessarily result in life becoming more advanced, only in propagating life that is suited for its particular niche. Animals don't tend toward complexity, only toward adaptations that suit their environment, which may or may not result in complexity.

Uh huh, nearly anything with 4 legs and warm blood can outrun us.

t. brainlet

he's talking about how long we can run, not how fast

endurance =/= speed

Show me a human that can run for longer than a horse.

xdd

en.wikipedia.org/wiki/Man_versus_Horse_Marathon

It depends where. The warmer and drier the climate/weather, the more of an edge humans have by sweating more. I think a man could run down a horse.

>horse wins nearly all the time
>comparing a horse with a human rider to an unburdened horse

also, consider natty life senses. no artificial flavors or odors to desensitize you, no loud music, cars, roads, industrial stuff, etc. maybe banging rocks together dulls certain frequencies.

no screens, artificial light, etc.

google man vs. horse marathon. and consider horses were bred to carry humans and cargo over distance, and any longer than a marathon, like say a double marathon and the human wins. because homo sapiens evolved as a persistence hunting/migratory species, literally walking for days or running our prey to exhaustion before smashing it with rocks or something.

>Humans win only twice
Kek, human endurance myth btfo. Humans confirmed for shittiest animals.

I think has a point, though.
Also, horses couldn't be considered a natural prey of out ancestors

dash.harvard.edu/bitstream/handle/1/3716644/Lieberman_Marathon.pdf?sequence=3

tl;dr humans have the fastest trot speed on the planet and can run the furthest thanks to sweat glands and lack of body hair especially in hot conditions, almost like we adapted to the climate conditions of the african plains

consider the athleticism of the runners though, I mean, yeah they MAY be in somewhat healthy shape for their age and for that small welsh town, but look at humans in the natural environment, where eating meant running, every day, not competing for a local marathon, not running because it's trendy or because your cholesterol is high or you are pre-diabetic,

google the Raramuri people of mexico, they can run the just under distance of washington to new york.

npr.org/sections/parallels/2013/11/01/241895965/how-one-kenyan-tribe-produces-the-worlds-best-runners

especially consider the high test levels of our early ancestors, they were all world class tier runners.

the whole hair and sweat stuff is debatable since body hair protects from UV radiation and requires more sweat to cool off. nobody knows really.

>and requires more sweat to cool off. nobody knows really.
If true, that's retarded.

Also, the human body is fragile and our sensitive spots and organs are exposed.
And our women are retarded when it comes to mate selection.

They were in the past, but now it's 2016 and we all know which group of men have the best seed.

then why do antelopes and shit have hair all over them? or chimpanzees in the dense brush under the jungle canopy? pretty sure horses and some primates can sweat too.

i'm guessing you aren't a hairy fellow whose been stuck in tropical heat?

i don't really get it though, it's got some utility in keeping warm but, compared to wolves, hares, bears, etc. it's a weak ass pelt. seriously, throw a naked hairy person, the hairiest you can find, in the woods in the winter, see if he comes back, Inuits and other northern people known to be particularily aren't hairy at all.

Proofs?

There is no specific evidence to suggest that humans are specifically pack hunters and ample evidence to disprove it. Wolves are pack hunters and they communicate just fine.

All of the physical adaptions; opposing thumbs, uprightness etc. are perfectly adapted to higher cognitive functioning. It is unlikely that this would be a random occurrence.

Humans have the ability to see with x-rays, ultrasound, gamarays, and at long ranges with telescopes. Arguably our cognitive prowess has allowed us to surpass all other animals on the planet in terms of these skills. If evolution is responsible for our intellectual prowess then it is also responsible for our advances in these fields. If not then evolution is still an undirected force, as it has failed to come up with these advances in and of itself.

>he believes in the random mutation meme

probably these guys
youtube.com/watch?v=826HMLoiE_o

Because we're smart you dumb nigger.

Yea a bloodhound can smell shit way better than I can but we can detect that same dog several miles away via technology.

Even when we didn't have that technology, we were smarter than every animal around and could fuck up anything we chose to. There's no reason for anything but our minds to evolve at this point since nothing but another human can truly challenge us.

People are born with better/worse than average sight all the time. Does it give them better chances of survival and reproduction? As long as the answer is no, humans as a whole won't develop better senses.

The real misconception there is that evolution produces species perfectly adapted, to anything, in any sense of perfect. Were that the case, invasive/introduced species would not be a problem.

Nope, it's more recombination and mixing. More of a scientific definition thing, i'll grant.

Evolution is not guided by traits humans find desirable. It's the environment that selects traits.

Evolution also only acts on a small number of traits with a small amount of selective pressure over a long period of time. Take the textbook example of pepper moths in england. The only trait selected for was colorl not how fast it could fly, not how well it could see, not how smart it was, but simply what color it was. That was it. Evolution has nothing to do with what humans consider "better" just what works. Evolution is not guided, it's a 'just enough to get by' mechanism. As long as you live and pass on your genes that's all that matters.

You are wrong about the "just enough to get by". It's not enough to just get by, your genes (alleles mostly) would die out eventually and more efficient genes would replace them.

It's not just about having some children, it's also about how many children you will have, and what quality of mates your children will be getting.

A mutation that allows you to have on average 6,3 children will be selected for if your neighbour's non-mutated part of the genome only averages 6,25 children in the long run and eventually the latter might be replaced entirely.

In millions of generations, even small advantages matter cause they pile up.

I'd say the reason we don't have eagle vision, dog olfactory system and elephant hearing, is that there would also be detrimental aspects to having them, like energy consumption (brains don't process information using 0 Wh and our skulls are pretty tightly packed already). For some animals these costs would be lower compared to the gains cause of different environments and strategies applied.

>If evolution is real then why do humans have such poor sight, sense of smell, and hearing?
What makes you think we are done evolving?
And who wanted heightened senses in prehistoric times? Everyone was ugly, stank and grunted or snored!

>If evolution is real then why do humans have such poor sight, sense of smell, and hearing?

If evolution isn't real why don't humans have extremely advanced RADAR antenae and embedded seismographs?

I do.

learn what evolution is ffs.

It's not like creating a character in a Game, oh yeah here some stats now here a lil talent.

It is not purposeful it is random.

read these too, you might get a much better understanding of evolution

(hater-fags, kill yourself, lol)

What are we supposed to have? Dog-level senses? Why don't dogs have even better senses? Why didn't we just cut out the middle man and evolve omniscience?

there are people that run 100 miles for fun

Why can't dolphin fly?

speak for yourself bro. I got fuckin eagle eye vision. My hearing is pretty solid too. As for smell i dont know why we'd need that.

And if you think about it. We probably have the best average of all the sense of any 1 animal. Dogs have great hearing and smell but terrible eye sight, and i mean terrible. We have a nice average of all 5

>single photon detection capabilities, full spectrum detection from above infra-red to below ultra violet, binocular vision with enhanced occipital cortex for advanced image and pattern recognition

Anything wrong in these? Wasn't too convinced when the Leibniz video said abstract objects couldn't be the creator of the universe.

Evolution is not random.

Natural selection is a non-random process.

>why would I need to smell if the food has gone bad?

underrated post

Does anyone here actually believe that our brains are the result of random mutation and natural selection? Because if you do then you're basically no different to religious people.

Because poor sight, sense of smell and hearing don't prevent you from reproducing.

Bait?

What type of brain would you accept as having evolved? Where do you draw the line? A single neuron? Ten neurons? Billion neurons? Worm brain? Chimp brain?

Brains are encoded by four types of nucleotides, ATGC. The human genome is just a sequence of these letters. Some of those sequences affect how the brain grows during your lifetime from a single cell into a huge complex organ. Which ATGC sequences do you think are impossible for mutations to form? Or maybe for natural selection to favor?

Why would say ATCATGTTGAATATA be impossible when mutations can delete any nucleotide and add any nucleotide to any position in the sequence?

What's near impossible is random mutations leading to a being that can ponder its place in the universe. There is no way that something as complex as the brain could have formed naturally, even over millions of years.
I find alien tampering to be much more plausible than random evolution.

Your ignorance is not an argument user. Just because you can't see how it could happen doesn't mean it couldn't happen.

Do you know how natural selection works?

Yes I do. But it's ridiculous to claim that incremental changes, most of which were beneficial at the time led to the modern brain. Do you realize how much design work goes into a microprocessor? How many problems have to be foreseen and accounted for in the design? The brain make a microprocessor look like a slide rule in comparison.

So tell me what is the maximum complexity achiavable using evolutionary processes over some X amount of time?

How complex can the brain really be, genetically, when there are only around 3.2 billion letters worth of DNA? And that's at least 80 % junk, so we have around 300 - 600 million nucleotides that actually do anything at all. And only a fraction of that has anything to do with the brain.

Humans and worms share a common ancestor that lived around 600 million years ago. Even worms have sophisticated brains with sensory inputs and hormone secretions and whatnot. Worms had around 2.5-3.5 billion years time to evolve worm brains and then some 0.6 billion years for humans to evolve our brain from worm brains.

That's only about 1 nucleotide change per year since life started. Or around 10 years per nucleotide that is actually functional. Maybe a few hundred years per nucleotide change that governs the brain.

Why would there not be enough time for complexity like this?

Or is there some process that says "Huh, this is complex enough, halt evolution here"?

So what if the brain is complex? It is still generated by the DNA and there is no pattern or sequence that cannot be generated using mutations.

Did humans evolve to be smart because of our relatively weak bodies...

Or did humans evolved to have weak bodies because we are smart?

We do? I thought our senses were good enough, not the greatest but still pretty good.

>weak bodies

Humans are actually relatively tough.

We got weaker (less muscle) after getting bigger brains, but it wasn't a single point in time, but more like a continuum of exchanging muscle mass to brain mass.

>So tell me what is the maximum complexity achiavable using evolutionary processes over some X amount of time?
I have no idea, and I'm pretty sure no one else does either.
>How complex can the brain really be, genetically, when there are only around 3.2 billion letters worth of DNA?
The Mona Lisa is also just lots of different colour pigments organized in an array, why couldn't someone flicking pain at a canvas have painted it?
>Or around 10 years per nucleotide that is actually functional
Christ you're dumb.

Not really. Get an average person to fight 1v1 without any tactics or weapons against any animal with the same size and the human will lose.

Compared to what? A chimp has 2 times the muscle strength per weight.

>Or is there some process that says "Huh, this is complex enough, halt evolution here"?

Evolution doesn't have an end goal. It doesn't care about complexity. What evolution is is a process that arises from imperfect reproduction. It is primarily driven by a natural tendency for those more capable of reproducing to continue to reproduce, whether the organism is unfathomably complex or very simple.

Someone flicking paint to a canvas is nothing like evolution. That would be a completely random process when evolution is not at all random.

Random process flicking random parts to existence and then assuming it would mysteriously form a car is stupid. But that same process combined with a non-intelligent selection algorithm can produce something like a car.

Compared to other mammals, humans have greater endurance, resistance to harsh climate and terrain, and recover and adapt to injuries better.

Nature is not a 1v1 fight.

...

> humans have greater endurance, resistance to harsh climate and terrain, and recover and adapt to injuries better.
No we don't. we have winter jackets, snow boots and camping tents. We don't have any evolutionary advantage on them if were left in nature.

Poor user... No girls have picked you? Were you picked last for kickball, dodgeball, and red rover too? Hmm. Correlation, or no?

Dogs don't care. Even with their sense of smell, they eat everything and vomit up the stuff they can't handle.

>The brain make a microprocessor look like a slide rule in comparison.

It works on different principles than a microprocessor. People are working since a long time on processors that can build their own pathways. This would allow them to become more complex and specialized than a processor by human design. Self-optimization is a powerful concept.

Also just because we can't build computers yet that outperform human brains in terms of interpretation and interaction with it's environment at the moment, doesn't mean we won't be able to build computers that can outperform brains in the near future. Eyes seemed for a long time like the most efficient unapproachably complex light sensors, since then we have developed cameras that outperform eyes in pretty much every aspect.

As some other anons pointed out already. We see different levels of brain complexity in animals. We can use these less complex brains as approximations of the evolutionary steps of the human brain. Relatively small changes can have a massive impact on processing ability of brain parts, given the self-optimizing nature of brains.

well see user, we didn't hunt horses, you retard

Humans had populated most of the globe before winter jackets had been invented.

If god made us, then why do humans have such poor sight, sense of smell, and hearing?

You don't understand what a million years are.

Humans can run longer distances over continues periods of time than pretty much any other animal. That's how persistence hunting works. That's how humans hunted down prey for thousands of years.

Humans can swim, climb trees and vertical rock walls. Depending on the environment a human would often win simply by outmaneuvering the animal.

Humans often punch sharks into submission. That's literally what you are supposed to do when a shark attacks you. Humans striking ability shouldn't be underestimated. A trained human can knock out a kangaroo.

Yes if you put a human into an open arena with a similarly sized animal, especially if it's a carnivore, with no weapons and no preparation time, then he will lose. But that's not how it goes in nature. Also humans usually hunted in groups like wolves.

>why do humans have such poor sight, sense of smell, and hearing?
We don't. Our eyesight's pretty good, and our hearing and sense of smell are both decent.

>Compared to animals that are "below" us, our senses are shit
Except they're not. Our sense of sight is shit compared to some animals, but it's better than most. Our sense of hearing is shit compared to some animals, but it's also better than most. Even our sense of smell, that we always completely discount as terrible, is actually pretty average when you compare it to all sorts of animals.

The same goes for animals. No creature is perfect.

>I'm saying that all animals except for humans improved physically
Improved from what starting point exactly?

>higher consciousness
This is also a meme. A bear doesn't have a human's brain, and a human doesn't have a bear's nose.

Basically because it costs more resource wise to develop those more advanced systems. What we are currently equipped with is good enough to keep the species going in our current environment, why spend extra on something that doesn't really impact survival?

Do you know why this marathon length is less than half the usual for human?

we're smart enough to extrapolate from incomplete sensory information where "lesser" animals need as much information they can.

>the whole hair and sweat stuff is debatable since body hair protects from UV radiation and requires more sweat to cool off. nobody knows really.
If nobody knows then it sure isn't for reasons as retarded as that.

>body hair protects from UV radiation
So does melanin.

>and requires more sweat to cool off
What do you mean, "more sweat"? That's what sweat is for in the first place.

Right, just like how Oetzi was bare-ass naked and had no clothes whatsoever near or on him when archaeologists discovered his corpse. Oh, wait.

Humans were persistance hunters, not pack animals. Our superiority didnt come from our ability to communicate just for hunting either. We could pass down memories, train and teach each other.

From the moment humans stopped shitting where they ate, we became the apex predators of the world.

actually, there is some evidence that humans can detect X-rays, and near IR, it's debated, inconclusive, leaning towards a non-functional yes.

yes, but with persistence hunting comes team-effort, chasing down a zebra to exhaustion is some tough shit, you better hope it doesn't outrun you 200km into the Serengeti rather have some people dispersed over a distance who can pick up some slack and keep it "penned" in a sense, share the meat, no need to cook it on the spot after running 3 marathons and not being able to hold it down, then fending off hyenas and moa birds and shit.

>What do you mean, "more sweat"? That's what sweat is for in the first place.
I don't understand the question, body hair retains heat, meaning, to cool down in a hot climate, one would need to sweat even more than someone who is bare skinned. meaning, sweat would "logically" develop with body hair.

go get prepared for your school, honey

>I don't understand the question, body hair retains heat, meaning, to cool down in a hot climate, one would need to sweat even more than someone who is bare skinned. meaning, sweat would "logically" develop with body hair.
No, that would logically lead to the elimination of body hair.
