The fictional Captain America was frozen and came back to life after about a few decades. Now in reality, roundworms from two areas of Siberia came back to life in Petri dishes after being frozen for 42,000 years.

Neanderthals were just going extinct about the time these worms were frozen.

The first human aboriginal settlements had not been made yet for another 2000 to 12000 years.

Some 300 prehistoric worms from permafrost were analyzed – and two 'were shown to contain viable nematodes'.

After being defrosted, the nematodes showed signs of life and then they started moving and eating.

The old homo sapien bones from outside Africa and the Middle east were from 50,000 years ago in Siberia.
