any remains of prehistoric life

Evolution is best described as a change

from a few simple organisms to great variety

How does the Earth's geologic past compare with the present?

In general, the changes we see now occurred in the past

How can we define evolution?

The development of many diverse lifeforms

How can we best provide evidence for organic evolution?

compare fossils of various ages from different rock layers

Why are index fossils used to determine geologic age of rocks worldwide?

They are in a single layer in all locations.

How would tropical seas during the early Paleozoic Era compare to similar environments today?

Environment would be the same; the living things different

The written history of human civilization
The change in one living thing throughout its lifetime
The development of many diverse lifeforms

A
B
C
D
10
How can we best provide evidence for organic evolution?
compare fossils of various ages from different rock layers
study rock layers to find missing parts of the rock record
use radioactive elements to age one fossil
use the law of superposition to age igneous intrustions
11

They are found in all layers in all locations.
They are found in all layers in one location.
They are in a single layer in all locations.
14
How would tropical seas during the early Paleozoic Era compare to similar environments today?
There were no tropical seas in the geologic past
Living things would be the same, the environment different
There would be no differences
