What is evidence of evolution?

Back

Evidence of evolution refers to the various types of data and observations that support the theory of evolution, showing how species change over time and share common ancestors.

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, leading to evolutionary changes.

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, indicating evolutionary relationships, such as the forelimbs of humans and whales.

What is embryology?

Back

Embryology is the study of the development of embryos, which provides evidence of evolution by showing similarities in early developmental stages among different species.

What are vestigial organs?

Back

Vestigial organs are body parts that have lost their original function through evolution, such as the human appendix, indicating a common ancestry with other species.

What does DNA similarity indicate about organisms?

Back

DNA similarity indicates how closely related two organisms are; the more similar their DNA sequences, the more closely related they are likely to be.

What is a common ancestor?

Back

A common ancestor is an ancestral species from which two or more different species have evolved, providing a link in the evolutionary tree.

What is the significance of fossil records?

Back

Fossil records provide evidence of past life forms and their evolution over time, showing changes in species and the emergence of new ones.

What is adaptive radiation?

Back

Adaptive radiation is the process by which organisms diversify rapidly into a variety of forms to adapt to different environments, often seen in species that colonize new habitats.

What is the difference between convergent and divergent evolution?

Back

Convergent evolution occurs when unrelated species develop similar traits due to similar environmental pressures, while divergent evolution occurs when related species evolve different traits.
