Evolution and Ecology Assessment Full

Match the following terms to their correct definitions:

• Change in heritable traits of a population over generations.

• 
• Random change in allele frequencies, strongest in small populations.

• 
• Study of how organisms interact with each other and their environment.

• 
• Sharp reduction in population size that alters allele frequencies by chance.

• 
• A heritable feature that increases fitness in a particular environment.

Organize these options into the right categories

Groups:

(a) Chance-based mechanisms

,

(b) Environment-selected mechanisms

• natural selection

• aritifical selection

• bottleneck effect

• genetic drift

• sexual selection

Bat wing vs human arm share bone pattern. This is:

• Convergent/analogous

• Divergent/homologous

Dolphin flipper vs shark fin with similar shape but different ancestry. This is

• Convergent/analogous

• Divergent/homologous

Many finch species on islands from one ancestor. This is primarily:

• Adaptive radiation (divergent)

• Coevolution

Hummingbirds and tubular flowers evolving complementary traits. This is:

• Coevolution/reciprocal adaptation

• Genetic drift

Which of the following correctly categorizes the biodiversity levels for the given examples?

Groups:

(a) Genetic diversity

,

(b) Species diversity

,

(c) Ecosystem diversity

• Coral reef fish species richness

• Range of habitats (marsh, swamp, pine forest) in a parish

• Number of amphibian species in a wetland

• Different coat-color alleles within a wolf population

• Variation in rice cultivars grown by farmers

Many offspring, little parental care, early maturity:

• A. r-selected

• B. K-selected

Few offspring, high parental investment, late maturity:

• A. r-selected

• B. K-selected

Humans generally follow:

• Type III

• Type I
