Right, so why hasn’t the human eye evolved and changed from what it was like 3.8 million years ago.
Since it is soft tissue, we have no way of knowing if the human eye has changed from what it was like 3.8 mya. One interesting feature of the modern eye is that around age 40 it begins to be more far sighted. This would be useful to help less mobile elders see danger clearly at a further distance so they can escape or move from danger. I used to be VERY nearsighted. Now I am only slightly nearsighted and may try to get me next drivers license without the glasses requirement.
I also wrote the answer below to someone at the original story who commented that they didn’t believe that evolution could move a creature from ape to human over millions of years.
“Out of many perfect cell division that take place, once in a great while a mutation takes place. With enough time and enough mutations, you eventually end up with something that is a little different from the original. For example, probably less than 10,000 years ago, some people from central Asia had a mutant gene that enabled them to drink milk well after childhood. This ability enabled them to drive their way into Central Europe and outsurvive the original population. This mutation became very common quite rapidly in the people who are now Europeans. It was a strong advantage to be able to drink milk during bitter winter weather, so a lot more lactose tolerant people survived than those who were not.”
