What are adaptations?

Back

Adaptations are physical or behavioral characteristics that help an organism survive and reproduce in its environment.

Front

What is natural selection?

Back

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

Front

What is speciation?

Back

Speciation is the process by which two populations of the same species become so different that they can no longer interbreed.

Front

What are homologous structures?

Back

Homologous structures are body parts in different species that are similar because they share a common ancestor.

Front

What are vestigial structures?

Back

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

Front

What is embryology?

Back

Embryology is the study of embryos and their development, providing evidence for evolution through similarities in early stages of development.

Front

What is a fossil?

Back

A fossil is the preserved remains or traces of ancient organisms, providing evidence of past life and evolution.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a population, which is essential for evolution.

Front

What is artificial selection?

Back

Artificial selection is the process by which humans breed plants and animals for specific traits.
