Evolution Flashcardizz

Front

What happens when species produce too many offspring?

Back

Only those that are best fit can survive.

Front

What is the mechanism of evolution that occurs when individuals migrate between populations?

Back

Gene flow.

Front

What is genetic drift?

Back

Change in the allele frequency of a population due to random chance.

Front

What are homologous structures?

Back

Features that share a common ancestor but have different functions.

Front

What are vestigial structures?

Back

Remnants of once-important structures that have slowly lost all or most of their function.

Front

What is natural selection?

Back

The process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the difference between analogous and homologous structures?

Back

Analogous structures perform a similar function but are not similar in origin; homologous structures share a common ancestor.

Front

What is extinction in the context of evolution?

Back

The end of an organism or a group of organisms, leading to the loss of biodiversity.

Front

What is the role of mutation in evolution?

Back

Mutations introduce new genetic variations into a population, which can lead to evolutionary changes.

Front

What is the significance of fossil records in understanding evolution?

Back

Fossil records provide evidence of past life forms and their changes over time.
