A group of organisms that can mate to produce fertile offspring.

The process by which the inherited traits of a population change over generations.

The preserved remains or traces of an organism that lived in the past.

An inherited trait that increases an organism's chance of survival and reproduction in its environment.

A well-supported explanation of some aspect of the natural world based on a body of facts and repeated testing.

The process where organisms with traits better suited to their environment survive and reproduce more successfully.

The struggle between organisms for limited resources like food, water, or territory.

A form of natural selection where individuals with certain inherited traits are more likely to obtain mates.

: Two or more species evolving in response to changes in each other over time.

The total collection of all discovered fossils, showing how life has changed over time.

An organism in its earliest stage of development before birth or hatching.

Body parts in different species that have a similar internal bone structure, indicating a common ancestor.

A term used to describe a species that no longer has any living members.

Body parts that have lost their original function through the process of evolution.

A technique that uses the mutation rate of DNA to estimate the time when two species diverged from a common ancestor.

Determining the age of a fossil or rock layer by comparing it to the positions of others

Determining the specific age of a fossil or rock in years, often through radioactive testing.
