00:00:03.467 --> 00:00:06.004
Fossil evidence is patchy
00:00:06.004 --> 00:00:11.007
so scientists don't know exactly where life holds on
00:00:11.007 --> 00:00:17.767
On land some life likely survived near the cooler poles
00:00:17.767 --> 00:00:22.634
And many creatures could have sought refuge underground
00:00:22.634 --> 00:00:25.000
sheltering from blistering temperatures
00:00:25.000 --> 00:00:27.007
and intense solar radiation
00:00:30.134 --> 00:00:33.999
And some life survives above ground too
