Amplify Evolutionary History Critical Juncture

The body structures for a population of chimpanzees were stable for a long time. Then, their body structures changed, making the chimpanzees stronger. Why did this happen?

• Organisms naturally become stronger over time.

• It is impossible to say without more information.

• The chimpanzee population wanted to be stronger.

• Their environment must have changed.

Imagine a population of frogs that live in the forest. The frogs have a green coloring on top that helps them blend into the forest so they are not noticed by predators. Imagine that half of this population stayed in the forest and the other half of the population moved to the hills above the forest, which are drier, with some brown grass and brown soil. Which population of frogs is likely to have more changes after many generations?

• Descendant Species 1: The frogs in the brown hills.

• Descendant Species 2: The frogs in the green forest.

• Neither.

What is the significance of a 'critical juncture' in evolutionary history?

• A point where significant evolutionary changes occur rapidly

• A period of extinction with no evolutionary changes

• A time when evolutionary processes slow down

• A phase where only minor evolutionary changes happen

How does a 'critical juncture' affect species adaptation?

• It accelerates adaptation to new environments

• It prevents adaptation to changing conditions

• It has no effect on species adaptation

• It causes species to revert to ancestral traits
