Evolution

Front

What is natural selection?

Back

Natural selection is the process by which organisms that are best adapted to their environment survive and reproduce more successfully than those that are less adapted.

Front

What is evolution?

Back

Evolution is the change in the heritable characteristics of biological populations over successive generations.

Front

What is extinction?

Back

Extinction is the state when a species completely dies out and no individuals are left.

Front

What are fossils?

Back

Fossils are the preserved remains or traces of organisms that lived in the past, providing evidence for evolution.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through the course of evolution.

Front

What is adaptation?

Back

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

Front

What is mutation?

Back

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

Front

What is embryology?

Back

Embryology is the study of embryos and their development, providing evidence for evolutionary relationships.

Front

What is the predator-prey relationship?

Back

The predator-prey relationship is the interaction between two species where one species (the predator) hunts and eats the other (the prey).

Front

What is the significance of genetic variation in evolution?

Back

Genetic variation is crucial for evolution as it provides the raw material for natural selection to act upon.
