According to Darwin studies natural selection only work by taking advantage of minor successive variation. It can never take a major and fast leap, but in gradual steps, it must continue rapidly and surely. So, according to Darwin evolution is a slow, gradual and continuous process.

Higher frequency of melanic British moths and DDT resistance in mosquitoes are cited as examples for
1 Arrival of the fittest
2 Genetic drift
3 Natural selection
4 Point mutation
Explanation:
Higher frequency of melanic British moths and DDT resistance in mosquitoes are cited for natural selection. Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adopted to their environment.

Darwins finches represent
1 Morphological variations
2 Geographical isolations
3 Climate variations
4 Reproductive isolation
Explanation:
There are thirteen type of finches described by Darwin. They are geographically isolated and found in Galapagos island of south pacific. Finch's beaks got modified according to their feed habit which shows bio geographical evolution suggesting that species restricted to a region develop unique features.
