Review for Evolution and Classification Test

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring. It is a key mechanism of evolution.

Front

What is comparative anatomy?

Back

Comparative anatomy is the study of the similarities and differences in the anatomy of different species, which helps to understand evolutionary relationships.

Front

Which species is most closely related to toothed whales?

Back

Baleen whales are most closely related to toothed whales based on DNA similarities.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry but may serve different functions.

Front

What is the significance of a time period of 10,000 years in evolution?

Back

A time period of 10,000 years is significant for evolution as it allows enough time for species to undergo substantial changes and adaptations.

Front

What is genetic equilibrium?

Back

Genetic equilibrium is a condition in which the allele frequencies in a population remain constant over generations, indicating no evolution is occurring.

Front

What is genetic mutation?

Back

Genetic mutation is a change in the DNA sequence of an organism, which can lead to new traits and potentially contribute to evolution.

Front

What is overproduction in the context of evolution?

Back

Overproduction refers to the phenomenon where organisms produce more offspring than can survive, leading to competition for resources.

Front

What are vestigial structures?

Back

Vestigial structures are anatomical features that have lost most or all of their original function through the course of evolution.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which organisms diversify rapidly into a wide variety of forms to adapt to different environments.
