Play an AI-generated podcast conversation about this lesson

What is the crux of Darwinism as mentioned in the text?

Passing on less favorable traits to offspring

Climate changes that favor all organisms equally

Inherent variation among offspring within the same species (correct)

Survival of all species without any changes

Which phrase succinctly summarizes the process of natural selection?

Random selection of traits

Survival of the fittest (correct)

Survival of the weakest

Competition of all species

What happens to organisms with less favorable traits according to Darwinism?

They have no impact on future generations

They can change their traits instantly

They are less likely to survive and reproduce (correct)

They are guaranteed to thrive in any environment
