What do gradualism and punctuated equilibrium have in common?
What do gradualism and punctuated equilibrium have in common? They are both explanations of the rate of evolutionary change. Studying the anatomy of different organisms allows scientists to determine how different species have evolved over time.
Why is punctuated equilibrium important?
Punctuated equilibrium is a theory used to justify coding, but time and variation won’t go away. It is a point in Darwin’s favor that the Origin of Species and natural selection both featured time and variation.
What type of evolution occurs at a slow constant rate?

Which organisms are most closely related?
Answer. Humans, chimpanzees, gorillas, orangutans and their extinct ancestors form a family of organisms known as the Hominidae. Researchers generally agree that among the living animals in this group, humans are most closely related to chimpanzees, judging from comparisons of anatomy and genetics.
What can natural selection not occur?
Natural selection can’t occur without variation and it acts on a _______. A species is an organism that has different features and cannot _______ with other organisms. It occurs when organisms with certain variations survive, reproduce, and pass their variations on to the next generation.
What are the process of natural selection?
Natural selection is the process through which populations of living organisms adapt and change. Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.
