What is evidence for evolution?

Back

Evidence for evolution includes various types of data that support the theory of evolution, such as fossils, genetic similarities, and anatomical structures.

What are fossils?

Back

Fossils are the preserved remains or traces of organisms that lived in the past, providing insight into the history of life on Earth.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, indicating evolutionary relationships.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through evolution, such as the human appendix.

Front

What is embryology?

Back

Embryology is the study of embryos and their development, which can reveal similarities between different species during early stages of development.

Front

How do fossils help determine the age of organisms?

Back

Fossils found in different rock layers can indicate the relative age of organisms, with deeper layers typically containing older fossils.

Front

What is the significance of DNA in evolution?

Back

DNA analysis can show genetic similarities and differences between species, providing evidence for common ancestry and evolutionary relationships.

Front

What does it mean when embryos look similar?

Back

When embryos of different species look similar, it suggests that they share a common ancestor and have similar developmental processes.

Front

What is the importance of comparative anatomy in evolution?

Back

Comparative anatomy studies the similarities and differences in the anatomy of different species, helping to understand evolutionary relationships.

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.
