Many farmers select their cattle for breeding, but some farmers allow natural breeding to occur. the jersey sire on this farm wasn’t selected by the farmer for mating. what’s the possible benefit to allowing natural breeding among cattle

1) increased likelihood the offspring will have traits the farmer desires
2) higher genetic variation among the offspring
3) lower genetic diversity among the population of cattle
4) decreased likelihood the offspring will choose its own mate in the future

higher genetic variation among the offspring

i would say it is

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
