Evidence for evolution
Fossils–the remains or imprints of animals and
plants preserved in rock–provide evidence for evolution. They show how
animals and plants have changed gradually through time. As we find more
fossils, the relationships between various kinds of animals and plants
become clearer.
We can tell when these elephants lived by
figuring out the age of their fossilized bones. Scientists cannot be
certain that the first type of elephant gradually evolved into the next,
but it is unlikely that each elephant appeared completely separately
from the others. It is much more likely that these elephants were
related.
Moenitherium lived about 38 million years
ago.
Trilophodon lived from 26 to 3 million years ago.
Platybelodon lived from 12 to 7 million years ago.
The woolly mammoth lived about two million years ago.
The African elephant is alive today.
