A classic example of natural selection at work is the origin of giraffes' long necks. The ancestors of modern giraffes were animals similar to deer or antelope, with necks of ordinary length.
Which of the following is the most recent example of evolution and natural selection? The development of pesticide-resistant insects.
Stabilizing, Directional, and Diversifying Selection. Stabilizing, directional, and diversifying selection either decrease, shift, or increase the genetic variance of a population.
The correct answer is E) It requires genetic variation, results in descent with modification, and involves differential reproductive success.

Blue eyes are another recent-evolved trait and scientists have determined it came from a mutation in a single ancestor 6,000-10,000 years ago. The mutation affected the OCA2 gene, which codes the protein necessary for producing melanin, which gives our skin, hair and eyes their color.Aug 3, 2016

The 3 Types of Natural SelectionStabilizing Selection.Directional Selection.Disruptive Selection.Apr 17, 2019
There are three types of natural selection that can occur. Stabilizing selection, directional selection or disruptive selection. Each one cause very different things to happen to the population.
The correct statement is – Natural Selection is the process by which 'organisms with more beneficial traits' are likely to survive and reproduce. EXPLANATION: Natural selection is the process of 'differential survival' and 'reproduction in organisms' that have different phenotype.Nov 28, 2021
A classic example of disruptive selection is the beak size of finches found on the Galapagos Islands. Peppered moths are also one of the most studied examples of disruptive selection.
The two most extreme outcomes of natural selection for species are extinction and speciation. Natural selection may cause populations of species to change, but exactly how they change depends on the specific selective pressures at a given time.Mar 26, 2016
