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

Where do adaptations come from?

The individual organism decides to adapt

Mutations that give an organism an advantage in its environment

Genetic recombination during meiosis

Both mutations and genetic recombination are sources of adaptation

Mutations are important because they bring about

death of the organism in which they develop

genetic variation needed for a population to evolve

benefits for the individual, not for the population

changes in genotype, but not phenotype

Before the invention of the light bulb, Americans burned oil in lamps for light. Whale oil was popular bio-fuel for these

lamps. Ship crews would hunt whales for their oil. They searched for the largest whales they could find so that they could obtain as much whale oil as possible. How mighty decades of whale hunting possibly affect the natural selection of the species?

The whales lost their legs.

The whales became slower.

The whales became smaller.

The whales changed their calls.
