Evolution review

Change over time...

• Evolution
• Nucleotide 

When looking at two birds of the same species, you notice that one has darker feathers than the other one. You also notice that one has a beak that is just a little longer. These slight differences within members of the same species are called.....

• Fossils

• Extinction

• Meiosis

• Variations

Who came up with the theory of Evolution by natural selection?

• Robert Hooke

• Charles Darwin

• Gregor Mendel

• Robert Virchow

A grizzly bear survives because he is well-adapted to his environment. When he reproduces he passes on those traits to his offspring. this process is called

• Natural Selection

• Selective Breeding

• Random mutations

• Variations in a species

Structures that share a common ancestry or are similar because they are modified versions of structures from a common ancestor that contain the same basic bone structure are

• Not related.
• Not homologous. 
• Homologous.
• Young in origin.

A yellow morph and green morph of an insect lives in the rainforest canopy. You would expect:

• the green population to increase and the yellow to decrease

• both populations should stay the same

• both populations will increase

• the green population to decrease and the yellow to increaseThis is a wrong answer

When an organism completely dies out, it is called.....

• Adaption
• Extinction
• Fossilization
• Mutation

Organisms produce more offspring than can survive

• Overproduction

• Variation

• Struggle to Survive

• Survival of the Fittest

• Inheritance of Traits

The differences among a species, like different bird beaks, are called

• genes.
• variations.
• traits.
• theories.

Which process leads to evolution?

• Natural Selection

• Artificial Selection

• Unlimited resources

• Competition
