Question pertaining to evolution and human eye sight

Question

First, I need to say I am not an expert in evolution, but have researched some. So this may sound naive to some, but it is something I have been pondering and would like respectable answers.

With evolution, which in earlier years was survival of the fittest, caused mutations in our genes to increase survival rates per our environment. I understand this question is not valid in the present because we do not have a need for night vision, but in earlier years of human life we learned to sleep while at night, since we did not have clarity in our night vision and would increase our chances of survival against the mammals that do have great night vision.

Why is it then that through evolution and mutations in our genes that humans did not evolve to develop better night vision? Why did we suffice to use our intelligence to understand it was better to sleep at night and stay out of prey’s grasp, instead of us evolving through our genetics to develop better night vision and overcome that obstacle in survival?

Any insight into this question would be greatly appreciated as I am very curious about this.

Thank You!

Answer 1

Evolution is a theory, not a faith or religion. Theory is a systematic collection of data that points to the most plausible explanation of the current data available. Religion is a set of moral constructs written by humans into stories. Faith is nothing more than choosing to believe in those stories for self support or interest. As far as the evolutionary model, there are many holes still needing to be filled. However, unlike religion, the evolutionary model does not contradict itself, it is only a compilation of data. Having an intelligent creator does not mean the theory of evolution is wrong. If an intelligent creator decided to set the rules for our known universe and let evolution occur following these set of rules then they could both be correct. Our research has indicated that humans are descendents of other species. If you base your assumptions on religion then eye site is not needed at all by humans and we could live solely on the guidance of a higher power. If you base your assumptions on the theory of evolution, then primates with enhanced ocular ability, or three color vision, had a higher chance of producing progeny using their ocular abilities for things such as foraging, and survival.
