Answer:

Crossing over is the process by which genetic material is exchanged by non-sister chromatids during meiosis.

Crossing over results in a new combination of genetic information for the cell for a specific trait.

Crossing over ensures that organisms are not identical from generation to generation.

Genetic recombination allows for a variation in genetic material that is passed through the generations.

Crossing over produces modern combinations of alleles. Not unused alleles but unused combinations which can result in modern phenotypes or expanded assortment of phenotypes. This way the there's expanded genotype/phenotype variety but the genuine qualities are still the same ones.

fiasKO [112]

The change in weather pattern caused forest to become sparse and hot weather caused the reduction of apes as they had less food and difficulty in surviving the climate.

Explanation:

In Miocene epoch volcanic mountain chains were created in Central Africa which abruptly changed the local weather.

The sea-level got drop due to global cooling of that time.

This resulted in continental drift making land connection of Africa with Eurasia.

The primates started migrating through this route.

The African forest become dry causing selective pressures in primates.

The cooler climate in Eurasia caused extinction and migration of primates to Africa in late Miocene epoch.

The hot and humid climate and less woodland caused a reduction in number of apes which were replaced by modern world monkeys.
