Anatomically modern humans didn't evolve during the last ice age (and evolved in Africa, which was, and is, hot).
2 Nearly all of his night visiion while surrounded by large carnivores that could all see quite nicely in the dark
Other apes also have poor night vision. We didn't lose night vision - not sure we ever had it.
3 Nearly all of his sense of smell while trying to make it as a land prey animal
Yes but our brain instead is optimized towards speech and fine muscle control, which are probably more useful.
4 Nearly all of his musculature, in an age when muscle mattered
We have enough musculature, and our physiques allow us to run and swim, which give us huge evolutionary advantages.
Thank you, next?
Your claim is as if those traits just were. Chances of them evolving are nil.
