Evidence for Evolution

Front

What is the evidence shown in embryology?

Back

Embryology provides evidence for evolution by showing similarities in the early development stages of different species, indicating a common ancestry.

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, even if they have different functions.

What are vestigial structures?

Back

Vestigial structures are remnants of organs or structures that had a function in an early ancestor but are no longer useful in the current organism.

How does common ancestry relate to evolution?

Back

The more two organisms have in common, the more recent is their common ancestor during their evolution.

What type of evidence do fossils provide for evolution?

Back

Fossils provide evidence of past life forms and show how species have changed over time.

What is the role of embryology in understanding evolution?

Back

Embryology helps illustrate the developmental similarities among different species, supporting the idea of common descent.

What is the relationship between species and common ancestry?

Back

Species that share a more recent common ancestor are more closely related than those that do not.
