He introduces the convention to distinguish a particular research tradition Laudan from other approaches to the biology of human behavior. Evolutionary psychology rests upon specific theoretical principles presented in section 2 below not all of which are shared by others working in the biology of human behavior Laland and Brown ; Brown et al. For example, human behavioral ecologists present and defend explanatory hypotheses about human behavior that do not appeal to psychological mechanisms e.

Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.

One of the earliest defining human traits, bipedalism -- the ability to walk on two legs -- evolved over 4 million years ago. Other important human characteristics -- such as a large and complex brain, the ability to make and use tools, and the capacity for language -- developed more recently.

Many advanced traits -- including complex symbolic expression, art, and elaborate cultural diversity -- emerged mainly during the pastyears. Physical and genetic similarities show that the modern human speciesHomo sapiens, has a very close relationship to another group of primate species, the apes.

Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa.

Most scientists currently recognize some 15 to 20 different species of early humans. Scientists do not all agree, however, about how these species are related or which ones simply died out. Many early human species -- certainly the majority of them — left no living descendants.

Scientists also debate over how to identify and classify particular species of early humans, and about what factors influenced the evolution and extinction of each species. Early humans first migrated out of Africa into Asia probably between 2 million and 1. They entered Europe somewhat later, between 1.

Species of modern humans populated many parts of the world much later. For instance, people first came to Australia probably within the past 60, years and to the Americas within the past 30, years or so. The beginnings of agriculture and the rise of the first civilizations occurred within the past 12, years.

Paleoanthropology Paleoanthropology is the scientific study of human evolution. Paleoanthropology is a subfield of anthropology, the study of human culture, society, and biology. The field involves an understanding of the similarities and differences between humans and other species in their genes, body form, physiology, and behavior.

Paleoanthropologists search for the roots of human physical traits and behavior. They seek to discover how evolution has shaped the potentials, tendencies, and limitations of all people.

For many people, paleoanthropology is an exciting scientific field because it investigates the origin, over millions of years, of the universal and defining traits of our species.

However, some people find the concept of human evolution troubling because it can seem not to fit with religious and other traditional beliefs about how people, other living things, and the world came to be.

Nevertheless, many people have come to reconcile their beliefs with the scientific evidence. Early human fossils and archeological remains offer the most important clues about this ancient past.

These remains include bones, tools and any other evidence such as footprints, evidence of hearths, or butchery marks on animal bones left by earlier people.

Usually, the remains were buried and preserved naturally.Machery’s view captures elements of both the sociobiological view and the evolutionary psychology view of human nature.

He shares the idea that a trait must be a product of evolution, rather than say social learning or enculturation, with both these accounts. It will contain an overview of what you have to say in comparing and contrasting the perspectives of Gerhard Lenski, Leslie White, and Alvin Toffler with respect to the evolution of technology.

Sep 29,  · The evolution of bat-pollinated lineages probably began in the Miocene, well after the first appearance of families that currently contain many such lineages.

Bat pollination is thus derived in most plant groups, and its evolution has entailed significant changes in the timing of anthesis, morphology, biochemistry and physiology of flowers.
