Evolution Test Review ACA

A type of natural selection that favors one extreme phenotype over the others, leading to a shift in the population's traits in a specific direction.

A type of natural selection that favors intermediate phenotypes and reduces variation, maintaining the status quo for a particular trait.

A type of natural selection that favors extreme phenotypes at both ends of the spectrum, potentially leading to speciation.

A mode of natural selection where individuals with certain inherited characteristics are more likely than others to obtain mates.

The intentional breeding of certain traits over others by humans, leading to changes in the traits of domesticated species.

A reproductive isolation mechanism where different species have different mating behaviors, preventing them from interbreeding.

A reproductive isolation mechanism where differences in reproductive structures prevent successful mating between species.

A reproductive isolation mechanism where species breed at different times, preventing them from mating.

A reproductive isolation mechanism where sperm and egg from different species are incompatible, preventing fertilization.

The youngest layer represents the most recent deposits and can provide insights into current environmental conditions and species present.
