Summative Flashcard Review

Front

What is stabilizing selection?

Back

A type of natural selection that favors average individuals in a population, reducing variation.

Front

Which species is most closely related to humans?

Back

Mice are the species most closely related to humans among the options provided.

Front

What is disruptive selection?

Back

A type of natural selection that favors extreme phenotypes over intermediate phenotypes.

Front

What trait is represented by 'A' in a cladogram?

Back

Eyes are the trait that should go where 'A' is on the cladogram.

Front

What trait was last developed according to the cladogram?

Back

Opposable thumbs were the last trait developed according to the cladogram.

Front

Define cladogram.

Back

A diagram that shows the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

What is the significance of opposable thumbs in evolution?

Back

Opposable thumbs allow for grasping and manipulation of objects, which is crucial for tool use and survival.

Front

Explain the concept of natural selection.

Back

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

Front

What is the difference between directional and stabilizing selection?

Back

Directional selection favors one extreme phenotype, while stabilizing selection favors the average phenotype.

Front

What does a cladogram illustrate?

Back

A cladogram illustrates the evolutionary relationships and common ancestry among species.
