Front

What is fitness in the context of evolution?

Back

Fitness refers to an organism's ability to survive and reproduce in its environment. It is a measure of how well-suited an organism is to its environment.

Front

Why are advantageous traits more likely to be passed onto offspring?

Back

Advantageous traits are more likely to be passed onto offspring because they increase the chances of survival and reproduction.

Front

What is speciation?

Back

Speciation is the process through which new species are formed.

Front

What is the balance between natural and sexual selection?

Back

Sexual selection increases reproductive success, while natural selection increases survival.

Front

What does the 'fancier' category correspond to in evolutionary processes?

Back

The 'fancier' category corresponds to female choice in mate selection.

Front

Define natural selection.

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

Define sexual selection.

Front

What is an example of a trait favored by sexual selection?

Back

Bright plumage in male birds is often favored by sexual selection as it attracts females.

Front

How does competition influence natural selection?

Back

Competition for resources such as food, mates, and habitat can lead to natural selection, as only the fittest individuals survive.

Front

What role does genetic variation play in evolution?

Back

Genetic variation is essential for evolution as it provides the raw material for natural selection to act upon.
