so would the middle of the line lizard be able to breed with both the older version and the newer one? why would certain adaptations like size of the animal or length of certain appendages affect genitalia or result in new body parts altogether?
I have 2 questions about evolution:

>so would the middle of the line lizard be able to breed with both the older version and the newer one?
There are things like mules and ligers and stuff, Sometimes even when the animals look pretty different they can still breed and other times they can look pretty similar and yet still can't. Also sometimes the offspring of too distant animals are sterrile.

Dunno what you are asking here maybe they are on the same chromosome or the changes both are effected by the same hormone or protein.

so things can change a little bit but they can't change a lot? That's not very logical

It's a much more fruitful discussion if you've read the basic concepts and educated yourself a little. Else you're just asking to be spoonfed
Austin Martinez
Are you dumb? The longer you wait, the more things change. I would suggest that you read up on the subject (as you are obviously still in high school or a troll) by starting with "The God Delusion" by Richard Dawkins. You can ignore his metaphysical philosophy and focus solely on the arguments he makes for the credibility of evolution as a scientific theory.

They can change a lot actually. The alteration of one gene can cause little to no change, the alteration of another can lead to an animal being born with no eyes or an animal being a lot smarter or dumber.
There's a gene called FOXP2 that exists in many vertebrates. Alterations in humans cause them to have a lack of control over their facial musculature, low IQ and most importantly extreme limiting in verbal communication.
The gene has been knocked out in lab tests with mice, causing them to be unable to communicate through ultrasound and dying early. Some mice have been modifyed with the human version of the gene. These mice had a better learnig aptitude compared to other mice. The diference of the human and the mouse gen is only three amino acids.
The FOXP2 in neanderthals and human is exactly the same, causing scientists to believe that neanderthals had human faculty of speech. This faculty of speech in humans is, based on the age of the gene, between 200'000 and 100'000 years old, the neanderthal developed it seperately.
If you want to have your questions answered better and deeper you should look on what experts write on it, with what methodology etc

whats wrong with asking you or someone interested to educate me? if you don't want to then fuck off and find a thread you like so the people interested can do it. some people actually enjoy teaching

How could eyes evolve from no eyes? They seem a bit complex. What organisms have the beginnings of eyes?

What organisms have the beginnings of eyes? I just want to see cool proto eyes, not argue about god.
