What is a hominid

any bipedal primate

What is an index fossil

a fossil found in rocks one time period

Index fossils are commonly found, widely distributed fossils that are limited in time span. They help in dating other fossils found in the same sedimentary layer. For example, if you find a fossil from an unknown era near a fossil from a known time, you can assume that the two species were from about the same time.

What causes gene flow

Movement of gametes causes gene flow, which is influenced by individuals moving into a population.

Which of the following would cause gene flow

Individuals moving into a population

Why does geographic isolation cause speciation

it prevents gene flow between populations

What does a mutation have the most impact on allele frequency

when the population is small apex answers

When is a genetic drift a major factor in evolution

When there is a bottleneck - APEX

How can islation lead to formation of new species

Allopatric Speciation (geographic isolation) can lead to the formation of a new species because the population is split in two smaller populations by a physical barrier (river, canyon, mountain...).

What groups is the smallest level of classification

genus

What principles is not part of Darwin's original theory of evolution by natural selection

Random processes are not part of the theory of evolution by natural selection.

What did the US and soviet union became important members of

The United Nations .

How you radioactive dating important for providing evidence for evolution

It allows scientists to organize the fossil record.

APEX;)

How does high biodiversity affect an ecosystem-

Biodiversity makes the ecosystem more stable.

Which organisms are most closely related Remember the name of an organism is in the form of a genus species

b. rana capito and rana clamitans

What happens a population is in Hardy-Weinberg equilibrium

allele frequency does not change. Apex

What is an example of genetic drift APEX

Random Chance

The curve on the left shows the height of a population of penguins The curve on the right shows the population five years later What has happened to this population

Directional Selection - APEX

which is a density-independent factor in controlling a population

C) apex

Which feature would you expect to find in a population in which sexual selection depends on male competition

Large Males (apex)

A fly has two alleles for the color of its eyes. The green allele is recessive, and is represented by blue allele is dominant, and is represented by p. If 28 of organisms are green , what is p

0.47 (apex)
