Evolution and Ecology

Macroevolution is where there are:

• Major evolutionary changes to an entire taxonomic group, over a long period of time

• Minor evolutionary changes to an entire taxonomic group, over a short period of time

• Major evolutionary changes to a species or small group of organisms, over a long period of time

• Minor evolutionary changes to a species or small group of organisms, over a short period of time

Microevolution is where there is:

• Major evolutionary changes to a whole taxonomic group, over a long period of time.

• Major evolutionary changes within a species or small group of organism, over a long period of time.

• Minor evolutionary changes to a whole taxonomic group, over a short period of time.

• Minor evolutionary changes within a species or small group of organism, over a short period of time.

Which of the following is NOT an example of a selective pressure?

• Changes to the environment

• Predators

• Competition for resources

• Competition for mates

• Spontaneous mutations

The bones in your hand, a bat's wing, a dog's paw, or a whale's flipper all share similar structures. These are known as:

• Homologous structures

• Heterozygous structures

• Heterologic structures

• Homeopathic structures

Evolution occurs over a long period of time - too long for humans to directly observe.

• True

• False

A population can be defined as:

• A group of organisms of the same species, living together in the same same and time.

• A group of organisms of the same species, living together in the same same and time, and are able to breed.

• A group of organisms of the same species.

• A group of organisms.

Which of the following is NOT a stage of speciation?

• Variation

• Isolation

• Selection

• Speciation

• Sequestration

In humans, wisdom teeth, tonsils and your appendix are all examples of:

• Vestigial structures

• Primitive structures

• Primary structures

• Embryonic structures

Which of the following is NOT a function of a genetic counsellor?

• They research new genetic diseases and develop medication

• They study genetic conditions

• They help people to understand their genetic family history

• They guide people in making decisions regarding genetic conditions

The number of individuals of a species that can live in an area, without environmental degradation occurring is the:

• Carrying capacity

• Absorption capacity

• Limitation capacity

• Bearing capacity
