What two important ideas did Darwin contribute to science?

• evolution happens in small, gradual steps

• simple organisms can develop (through several generations) into more complex organisms

• species change over many generations to become better adapted to new conditions

• organisms that move to a different location will slowly adapt/evolve to better survive that new location

a well tested explanation for a wide range of observations and experiment results

• species

• evolution

• fossil

• adaptation

• scientific theory

Lamarck's theory of transformation, that parents could change their bodies physically and then pass that down to offspring, was proven . . .

• false

• true

What is the main idea of Darwin's theory of evolution?

• Organisms change over time due to random events.

• Evolution happens in large leaps every few million years.

• Species evolve through the process of natural selection.

• The strongest animals survive, while the weaker ones do not.

Why is Darwin's theory of evolution considered a theory?

• Because it is just a guess.

• Because it has been disproven.

• Because it is an explanation of natural phenomena supported by a large body of evidence.

• Because it is a law.

The two main themes learned from Darwin mentioned in the video are that

• A) All living things are independent evolution is random

• B) All living things are related and evolution is powered by natural precesses

• C) All living things are unique and evolution is a myth

• D) All living things are the same and evolution is a choice

Why do modern whales not have back legs, according to the video?

• They evolved to be more efficient swimmers

• They never had legs

• They lost them due to a genetic mutation

• They are born without them
