Homo habilis was likely the first hominid species to use modified stones to kill and skin animals. This provides immediate evidence for which major trend in hominid evolution?

Use of language as an adaptation

Increased brain size and complexity

Ability to walk upright on two legs

Bipedalism is an adaptation which mammals have obtained that allows them to walk on two legs. What advantage did the development of bipedalism most likely confer to early hominids?

It allowed them to move and hold tools at the same time.

It allowed them to see with binocular vision.

It allowed them to evolve a complex social structure.

It allowed them to evolve an opposable thumb.

Why do frogs and other organism reproduce so many eggs or offspring?

the more offspring the more likely the offspring will survive

so that their babies can have friends to play with

the more offspring the less likely offspring will survive

the more offspring the less competition

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

Because they are more likely to survive and reproduce.

Because they come from dominant alleles.

Because they come from recessive alleles.

Because the trait is an acquired phenotype.

Do organisms "decide" to evolve and change?

No, they change because of natural selection

Yes, they know they need to change to survive

Mutations are important because they bring about

genetic variation needed for a population to evolve

death of the organism in which they develop

benefits for the individual, not for the population

Hardey-Weinberg equilibrium within a population

The theory of evolution by natural selection means that what is changing over time?

The inherited traits of a population.

The acquired traits of a population.

Why is the mouse population changing over time?

The hawks eat more light mice than dark mice because they can see the light mice more easily

The light mice can reproduce more successfully than the dark mice

The hawks eat more dark mice than light mice because the dark mice taste better

The hawks eat more dark mice than light mice because they can see the dark mice more easily

Where do adaptations come from?

Mutations that give an organism an advantage in its environment

The individual organism decides to adapt

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?

Both will be equally successful

A virus killed most of the seals in the North Sea (e.g. dropped the population from 8000 to 800). In an effort to help preserve the species, scientists caught 20 of the remaining seals and used them to start a new population in the northwest Pacific Ocean. Which of the following statements would accurately describe the new population?

The new seal population is genetically less diverse than the original population

The new seal population is genetically more diverse than the original population

There is equal genetic variety compared to the original population

Genetic drift is change in the allele frequency of a population due to...

non-random mating (sexual selection)

Which of the following is true?

Gene flow can cause new alleles to enter a population's gene pool.

Gene pool frequencies do not change as a result of migration in or out of a population.

Gene flow occurs only as a result of isolation of a small population.

Gene flow is due the the selection of the most favorable traits.

The Aztecs and Maya Tribes of Mexico where some of the first humans to slowly change wild corn to the corn we know today. What process did these tribes use?

Artificial Selection "Selective Breeding"

Scientist have created larger and sweeter strawberries for humans to consume (eat). What process was used?

Environmental Natural Selection

Scientists have found evidence that about 2.4 million years ago a gene regulating jaw muscles mutated and may have led to the more graceful human jaw we see today. The diagram below shows the skulls of 3 hominid species.Which statement below most closely explains the link between jaw size and hominid evolution?

The jaws of hominids evolved to be smaller and less protruding over time.

The jaws of hominids evolved to be larger and more protruding over time.

There appears to be no change in the jaws of hominids over time.

The jaws of hominids changed over time due to a change in brain size.
