What is the Theory of Evolution?

Back

The Theory of Evolution explains how species change over time through processes like natural selection and genetic variation.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through evolution, such as the wings of an ostrich.

Front

What is the fossil record?

Back

The fossil record is the collection of all known fossils, which provides evidence of past life and evolutionary changes.

Front

What is extinction?

Back

Extinction is the permanent loss of a species when all its members die.

Front

What are fossils?

Back

Fossils are the preserved remains or traces of ancient organisms, often found in sedimentary rock.

Front

What are homologous structures?

Back

Homologous structures are body parts in different species that share a common ancestry, like the forelimbs of humans and whales.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is adaptation?

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

What is variation in biology?

Back

Variation refers to the differences in traits among individuals in a population, which can lead to evolution.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism, which can lead to new traits.
