What are some real world examples of natural selection?
Examples of Natural Selection Examples in Animals Galapagos finches have different types of beaks. During times of drought, the finches with the larger beaks survived better than those with smaller beaks. During rainy times, more small seeds were produced and the finches with smaller beaks fared better.
Is war a form of natural selection?
With casualties of that magnitude, evolutionary psychologists argue, war has served as a mechanism of natural selection in which the fittest prevail to acquire both mates and resources. This perspective has achieved broad influence.

How did the rat snake go through natural selection?
These snakes have recognizably different populations throughout different areas in Eastern North America. The most debatable topic is whether the rat snake should be a species or a subspecies. These populations all go back to one species because mating can occur between adjacent populations causing gene pool.
Is war caused by human nature?
There is no scientific proof that war is ingrained in human nature, according to a Rutgers University-Newark study. There is no scientific proof that humans are hardwired to go to war, says R. Brian Ferguson, professor of anthropology at Rutgers University-Newark. War, he says, may not be in our nature at all.
What is natural selection explain with example?
What is 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 adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds.
What is social Darwinism explain the organic analogy as given by Spencer?
The Organic analogy which is a staple of ancient and medieval thought was reformulated by Spencer. He regarded the recognition of the similarity between society and organism as the first step towards a general theory of evolution. The same definition of life applies to both biological and social organism.
How did giraffes evolve through natural selection?
A Darwinian theory of evolution posits that it was through random variation that some giraffes had longer necks than others. Thanks to their long necks, they were able to reach leaves high up in the trees in their environment.
What natural selection do warrior ants have?
Is war a human invention?
