Evidence of Evolutionary Notes

Front

What are analogous structures?

Back

Structures that have similar functions but do not share a common ancestor.

Front

What is common ancestry?

Back

The concept that different species share a common ancestor from which they have evolved.

Front

What are vestigial structures?

Back

Remnants of organs or structures that had a function in an early ancestor but are no longer functional.

Front

What is variation in populations?

Back

Differences in traits among individuals in a population, which can occur from one island to another.

Front

What are structural patterns?

Back

Clues to the history of a species, often observed in the physical characteristics of organisms.

Front

What is the significance of fossils in evolution?

Back

Fossils provide evidence of past life forms and their evolutionary changes over time.

Front

What are homologous structures?

Back

Structures that are similar in different species due to shared ancestry, even if they have different functions.

Front

How does embryology provide evidence for evolution?

Back

Similarities in embryonic development among different species suggest a common ancestry.

Front

What role does geography play in evolution?

Back

Geographical barriers can lead to variation and speciation among populations.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures share a common ancestor; analogous structures do not.
