United States. Spencer based his ideas upon the theory of evolution advanced by Charles Darwin. This theory held that all biological organisms evolved over the course of millions of years and that those species that were best able to adapt to the natural environment survived. Spencer broadened this concept to include all social‚ as well as biological organisms‚ and asserted that society evolved by adapting to the environment through social selection. William Graham Sumner was a professor of political

Kin Selection vs. Multilevel Selection In The Social Conquest of Earth by Edward Wilson‚ he argues that kin selection is not a valid theory and proposes a better theory called multilevel selection. This has been seen as a controversial proposal because for generations previous to multilevel selection‚ kin selection was the standard explanation of evolution. Through the use of various examples‚ Wilson makes a convincing pro-multilevel-selection argument. Kin Selection‚ also known as inclusive fitness

Charles Darwin was a scientist who did not know his theory and research would be the base of our understanding of evolution. Darwin discovered many things he did not know would explain many different aspect of natural selection. Darwin’s research manifests many interesting facts I did not know about until the explanation in the video Evolution What Darwin Never Knew.

However‚ through further thought‚ artificial selection can have a large impact if used and is important in the science world. Artificial selection is a process if breeding when “humans‚ not nature‚ choose the characteristics that we want to develop ion plants

can be written as \mathbf{v}_0 = v_{0x}\mathbf{i} + v_{0y}\mathbf{j}. The components v0x and v0y can be found if the angle‚ ϴ is known: v_{0x} = vgh_0\cos\theta‚ v_{0y} = v_0\sin\theta. If the projectile’s range‚ launch angle‚ and drop height are known‚ launch velocity can be found by V_0 = \sqrt{{R^2 g} \over {R \sin 2\theta + 2h \cos^2\theta}} . The launch angle is usually expressed by the symbol theta‚ but often the symbol alpha is used. Kinematic quantities of projectile motion

NATURAL LAW ROBERT P. GEORGE* Oliver Wendell Holmes‚ the legal philosopher and judge whom Richard Posner has‚ with admiration‚ dubbed “the American Nietzsche‚”1 established in the minds of many people a certain image of what natural law theories are theories of‚ and a certain set of reasons for supposing that such theories are misguided and even ridiculous.
