Evidence of Evolution

Front

What is evidence of evolution?

Back

Evidence of evolution refers to the various types of data and observations that support the theory of evolution, including fossil records, genetic similarities, and anatomical structures.

Front

What are homologous structures?

Back

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

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 common ancestry?

Back

Common ancestry is the concept that different species have descended from a shared ancestor.

Front

What is the significance of DNA similarities in evolution?

Back

DNA similarities among species indicate how closely related they are and provide evidence for common ancestry.

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.

Front

What is the fossil record?

Back

The fossil record is the collection of all known fossils and their placement in the earth's rock layers, providing evidence of past life and evolution.

Front

What is the difference between homology and analogy?

Back

Homology refers to similarities due to shared ancestry, while analogy refers to similarities due to convergent evolution, where different species develop similar traits independently.

Front

What is embryology in the context of evolution?

Back

Embryology is the study of the development of embryos, which can show similarities between different species, indicating common ancestry.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which a single ancestor species rapidly diversifies into a wide variety of forms to adapt to different environments.
