Question

Describe two examples of how humans have influenced natural selection in species.

Answer 1

Human has influenced natural selection by ‘selective breeding’ to make the physical appearance and behaviour of different organisms such as dogs, cabbage and pigeons. According to Darwin one of the most important features is the domestication of species for our own interest.

Pigeons, dogs, and cabbage are selectively breeded from common ancestor species Columba Livia(rock dove), dogs from Canis lupus ( wolf.), and cabbage from wild cabbage respectively.
