Climate Effects on Human Evolution

But there are no laws in the usual scientific sense determining the course of evolution. It deceives us into believing in the "eternality" of a single moment in nature. In the primordial and socially formative world that we must still explore, other of humanity's biological traits were to be reworked from the strictly natural to the social.

The Social Media Revolution: Modified by Jason A.

The replacement of the specialized species by closely related animals that possessed more flexible adaptations during a time of wide fluctuation in climate was a key piece of initial evidence that led to the variability selection hypothesis.

Perhaps we hear the rags to riches story on television time and again. When there are only a few fossils, the course of evolution may appear simple; but when the record is rich, biological history appears as an incredibly complex web of adapting organisms.

Points were hafted, or attached to handles such as spear or arrow shafts, and were later used as part of projectile weapons, which allowed hominins to hunt fast and dangerous prey without approaching as closely.

In addition to the species A. With time we can expect to increase our taxonomic and predictive power by using these causal bio-social theories of individual differences. Again, insofar as Wilson and the other sociobiologists are being purely speculative this criticism may be warranted: Second nature is the way in which human beings as flexible, highly intelligent primates inhabit the natural world.

In general, humans behave more altruistically in the biological sense towards their close kin than towards non-relatives, e. Bowles and Gintis At a time when a blind social mechanism, the market, is turning soil into sand, covering fertile land with concrete, poisoning air and water, and producing sweeping climatic and atmospheric changes, we cannot ignore the impact that a hierarchical and class society has on the natural world.

The early history of Old World monkeys remains very poorly understood, and much of the known earliest material has not been described. Any evolutionary explanation of how a phenotypic trait evolves must ultimately show that the trait leads to an increase in frequency of the genes that code for it presuming the trait is transmitted genetically.

In these locations, hominin groups encountered distinctly different environments, different plants and animals and foods, and different climatic conditions — a very wide range of temperature and strong variations in aridity and monsoonal rains.Evolutionary psychology attempts to explain human motivations and behavior as being the consequence of evolution.
