Lose his fur coat while ice ages were going on.
Lose almost all of his sense of smell while trying to make it as a land prey animal (fatal by itself).
Lose almost all of its night vision in an age when night was the only time of day to be had.

How do you know if the ancestor of modern humans had fur?
How do you know that ancestors of modern humans had an acute sense of smell? We do fine with our good eyesight and team work. So do chimps.
Where do you get the notion that it was dark all the time?

So, are you an ancient alien fan or a creationist?

“How do you know if the ancestor of modern humans had fur?”

Are you being serious with this question?

The Semi-Aquatic Human Theory explains many of these things.

They didn't. The statement I made was basically in subjunctive mood: IF there were such a thing as a human ancestor (there isn't), i.e. some hominid evolving into humans, THEN he would have to have lost his sense of smell, his night vision, and his fur.

In real life, wherever humans, apes, monkeys, or hominids appear in the universe, they appear looking as they do now or, in the case of hominids, as they did when they lived here. I provided a link for a book which explains some of this stuff...
