NARRATOR More evidence is found in fossils
00:00:03.009 --> 00:00:07.534
from the Grand Canyon
00:00:07.534 --> 00:00:10.134
So the fossil remains in this rock
00:00:10.134 --> 00:00:14.001
are little casings of organisms
00:00:14.001 --> 00:00:16.006
that look remarkably like
00:00:16.006 --> 00:00:19.367
a modern group of organisms that live today
00:00:19.367 --> 00:00:25.467
called testate amoebae that are voracious predators
00:00:25.467 --> 00:00:29.734
NARRATOR They make holes in cells to suck out their prey
00:00:29.734 --> 00:00:31.009
suggesting that something similar
00:00:31.009 --> 00:00:36.467
may have been eating ancient eukaryotes
00:00:36.467 --> 00:00:40.567
If true this would have changed everything
00:00:41.734 --> 00:00:43.001
SANDERS Predation
00:00:43.001 --> 00:00:44.634
just like environmental pressures
00:00:44.634 --> 00:00:49.834
can push life to experiment and try new things
