If you look at the universe and study the universe, what you find is that there is no evidence that we need anything other than the laws of physics and the other laws of science to explain everything we see. There's absolutely no evidence that we need any supernatural hand of god. -- Lawrence Krauss, World-Renowned Physicist
There is probably no other notion in any field of science that has been as extensively tested and as thoroughly corroborated as the evolutionary origin of living organisms. -- Encyclopedia Britannica
FAITH. No one word personifies the absolute worst and most wicked properties of religion better than that. Faith is mind-rot. It’s the poison that destroys critical thinking, undermines evidence, and leads people into lives dedicated to absurdity. It’s a parasite regarded as a virtue. -- PZ Myers
Religion is the antithesis of science, an anesthetic for the mind that disables critical thought and encourages the acceptance of inanity as fact, and wishful thinking as evidence. -- PZ Myers

Unneeded genes eventually get bumped off by mutations.

Why can't human apes (and their ape and monkey cousins) manufacture their own vitamin C like some other species can?

Why do our mouse cousins have a much better sense of smell than human apes?

As usual evolution by natural selection explains everything.

Apes (including people) and monkeys don't manufacture their own vitamin C because they don't have to. They have lived for millions of years in an environment where there has been plenty of fruit to eat. When mutations made those genes inactive, the creatures continued to survive and reproduce. Those same creatures would have died if not for the abundance of fruit, but instead they lived and so those inactive genes were passed on to the next generation.

We can't smell like the mice can because our ancient ape ancestors had color vision and so they didn't need a strong sense of smell. Those genes became inactive and were inherited by future generations including our species.

For a much better and much more thorough explanation see the section "Dead Genes" on pages 66 thru 73 of Jerry Coyne's Why Evolution is True.

Christian tards, don't bother with it. You're too bloody stupid to understand anything.
