100

A process by which favorable traits tend to increase in frequency over time is called

What is natural selection?

100

This is changes in a population's gene pool over time

What is evolution

100

These structures resemble each other due to similarity in function but lack similar structure.

What is Analogous structures?

100

When individuals at only one end of a bell-shaped curve of phenotype frequencies have high fitness, the result is ___________ selection

directional selection

100

According to fossil records, the horses that lived 50 million years ago were much smaller, weaker and slower than modern horses. Which process is most likely responsible for the changes that have led to the increased size, strength, and speed in horses?

What is Natural Selection

200

Differing traits in the same species

What is variation?

200

The similarity in homologous structures between different species is evidence that they

share a common ancestor

200

Structures thought to be without purpose or function such as auricular muscles and pelvic bones in snakes and whales. 

Vestigial structures

200

According to Darwin’s theory of natural selection, the individuals that tend to survive are those that have

traits better adapted to their environment (fitness)

200

The diagram illustrates an embryonic stage of two organisms.

Which of the following can be determined by observing the embryos shown in the diagram? 

The organisms share a common ancestry.

300

This is a heritable trait that increases an individuals fitness

What is an adaptation?

300

This type of evolution results in random changes in DNA becoming ultimate sources of new alleles

What is a mutation?

300

Diagram showing evolutionary relationships between organisms

Evolutionary tree or cladogram

300

(daily double)What type of distribution of phenotypes is described and shown in the graph?


What is stabilizing selection?

300

How would you explain the link between jaw size and hominid evolution? (daily double)

 As the hominid evolved the jaws got smaller and less protruding

400

More offspring are produced than can possibly survive

What is overproduction?

400

This type of evolutionary theory says that evolution happens steadily in tiny changes over long periods of time leading to species formation 

What is gradualism

400

The scientific theory of evolution is supported by different types of evidence. The diagrams below show the skeletons of two different animal species. How does comparing the skeletons of these animals provide support for the scientific theory of evolution?

It shows possible common ancestry between organisms.

400

A small population of chimpanzees lives in a habitat that undergoes no changes for a long period. How will genetic drift probably affect this population in terms of diversity?

What is reduce genetic diversity?

400

When faced with a change in enviornmental condition, a population of a species will do three things

What is MAD (migrate, adapt or die)

500

 This theory agrees with fossil records that show no intermediate forms for long period of time, in other words, periods of rapid change are separated by periods of little or no change

What is punctuated equilibrium

500

(Daily double) These are the four mechanisms of evolution

What is genetic drift, gene flow (migration), mutation, natural selection

500

Which of the following evidence of evolution provides the best scientific evidence that chimpanzees and rhesus monkeys come from a common ancestor?

DNA sequence (Protein Sequence or genetic sequence)

500

Mutations within a DNA sequence would best be described by which option

-increase genetic diversity

-alter phenotypes

-harmful variations

-lead to genetic superiority

What is increase genetic diversity?

500

Which statement can be inferred from the evolutionary tree?

Species 5 is most closely related to species 6
