By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.As a member, you'll also get unlimited access to over 55,000 lessons in math, English, science, history, and more.
As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils.
A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved.
The universe is full of naturally occurring radioactive elements.
Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms." When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside. By measuring the quantity of unstable atoms left in a rock and comparing it to the quantity of stable daughter atoms in the rock, scientists can estimate the amount of time that has passed since that rock formed.
Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation.
