Evolution

Dolphins have the same arm structure as wolfs, what type of evidence for evolution does this represent?

• DNA
• vestigial structures
• homologous structures
• embryology

Change over time is

• evolution
• generation
• growth
• biogenesis

What animal is Darwin known for studying?

• dinosaurs
• tunicates
• finches
• horses

Natural selection is

• survival of the fittest
• humans change
• two species are the same
• more animals survive

What is one reason that strawberries are surviving in the winter season?

• they have larger leaves
• they have genetic variations allowing them to be resistant to cold
• they reproduce more
• the color is dark

Who was Charles Darwin?

• A naturalist who came up with the theory of evolution
• A scientist who studied plants
• A geologist who looked at rocks and fossils
• A paleontologist who studied dinosaurs

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
• Hardey-Weinberg equilibrium within a population

1.  Darwin observed 13 species of finches on the Galapagos Islands.  What did Darwin conclude about the finches?

• a.  They evolved from a common ancestor.
• They all came from different continents.
• they evolved from 13 different types of birds.
• they developed from other types of organisms.

A spider may produce hundreds of eggs, only a few  of which may survive.  This is an example of 

• overproduction
• specialization
• genetic change
• division

Which of the following is an example of selective breeding?

• populations of lizards that have a certain trait become more numerous after a change in climate
• a population of insects develops resistance to a pesticide after farmers repeatedly use the same pesticide to kill the insects
• a population of bacteria develops resistance to an antibiotic
• farmers allow only sheep that produces the best wool to breed.
