Evolution

Question 1

Evolution

Answer 1

Is the change in genetic composition of a population during successive generations may result in development of new species.

Question 2

Evolutionary Radiation

Answer 2

An increase in taxonomic diversity that is caused by elevated rates of speciation, that may or may not be associated with an increase in morphological disparity.

Question 3

Mass extinction

Answer 3

Is when a species vanish much faster than they are replaced.

Question 4

Differentiate between evolutionary radiation and mass extinction

Answer 4

Evolutionary radiation is the increase in species population whereas mass extinction is the decrease in species population.

Question 5

Microevolution

Answer 5

Microevolution is small-scale variation of allele frequencies within a
species or population, in which the descendant is of the same
taxonomic group as the ancestor.

Question 6

Macroevolution

Answer 6

The variation of allele frequencies at or above the level of species over geological time.
e.g - Types of mammals
