Evolution and Natural Selection

submitted by: KatherineT

One of the many amazing aspects of science is that it provides an explanation as to why the animals we see today are the way they are. Through science, evolution and more specifically natural selection show that each organism is specifically engineered over time to more successfully survive in its given habitat. Without science, we would never understand the process of evolution or understand the world around us.

Anthropology and Parallelism : The Individual as a Universal

submitted by: hsrikm
It is difficult to define perspective within sets that are self belonging.

A Model of Genetic Variation in Human Social Network

submitted by: dougramsey
Social networks influence the evolution of cooperation and they exhibit strikingly systematic patterns across a wide range of human contexts. Both of these facts suggest that variation in the topological attributes of human social networks might have a genetic basis. While genetic variation accounts for a significant portion of the variation in many complex social behaviors, the heritability of egocentric social network attributes is unknown. Here we show that three of these attributes...

Apparency and Actuality

submitted by: hsrikm
Apparency and actuality are discussed with respect to science, genetics, evolution, cognition and perception. Rules for a (sub)set of actual/allowable sets of entities and objects from a total set that is based on differences and contrasts extracted from perceptual experience of the world elucidate tenable combinations/recombinations from a total of the transparent(history/past dependant) and the apparent as they can be construed to comprise the actual/real faces of perception. The elements...
