Review It - Natural Selection

These cause variations

• mutations
• a desire to change
• adaptations
• injuries

Where did Charles Darwin travel to on his voyage?

• Australia
• Barbados
• Galapagos
• Trinidad

Humans breed plants and animals to have desirable traits. This is called:

• Natural Selection
• mutations
• selective breeding
• common descent

The idea that all life has come from the same ancestor is called

• Natural Selection
• mutations
• selective breeding
• common descent

A slight difference in an inherited trait between individual members of the same species.

• variations
• homologous structures
• adaptations
• vestigial structures

An inherited trait that increases an organism's chance of surviving and reproducing.

• variation
• vestigial structure
• adaptation
• mutation

What did Darwin notice about the tortoises on the Galapagos Islands?

• The tortoises on islands were the same as the ones on the mainland
• the tortoises on different islands were different species, but were similar to the ones on the mainland
• the tortoises had extreme differences to those on the mainland.

When an organism of a species has an adaptation, it will compete for resources better, survive longer and pass that adaptation on to it's offspring. This process is called

• natural selection
• inbreeding
• artificial selection
• outbreeding

Survival of the fittest and evolution were proposed by which scientist?

• Charles Darwin
• Steven hawking
• Albert Einstein
• isaac newton

Why are advantageous traits more likely to be passed onto offspring?

• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.
• Because they come from dominant alleles.
• Because they are more likely to survive and reproduce.
