Evolution and human beings

Found in it has been dated to approximately 18, years old. One line of attack on H. Shorter and less flexible toes functioned as rigid levers for pushing off the ground with each step.

Accordingly, human bipedalism is a natural development from the basic arboreal primate body plan, in which the hind limbs are used to move about and sitting upright is common during feeding and rest. To walk, one simply tilts forward slightly and then keeps up with the displaced centre of mass, which is located within the pelvis.

The australopiths had an S-shaped spine that allowed for balance when standing. However, more recent evidence suggests a different story. In any case, our ancestors were not strictly or even heavily carnivorous.

Bone size, shape, and markings left by muscles tell us how those predecessors moved around, held tools, and how the size of their brains changed over a long time. He noted that all organisms compete with one another for food, space, mates, and other things needed for survival and reproduction.

Both had curved fingers and long thumbs with a wide range of movement. Facebook comments preferred; negative anonymous comments will not display. Indeed, our large buttock, anterior thigh, and calf muscles are virtually unused when we stand still.

Unlike other primate feet, which have a mobile midfoot, the human foot possesses if not requires a stable arch to give it strength. Facebook comments preferred; negative anonymous comments will not display. Evolution does not change any single individual.

Curved ilia situate some of the gluteal muscles on the side of the hip jointwhere they steady the pelvis as the foot swings forward during a step.

This figure is the result of studying the genetic makeup of humans and apes, and then calculating approximately how long it took for those differences to develop.

The earlier specimens from 1. It is from Georgia and may be an intermediate form between H. Humans have short ischia and long lower limbsfacilitating speedy actions of the hamstring muscles, which extend the thigh at the hip joint, while great apes have long ischia and short hind limbswhich give them powerful hip extension for climbing up trees.

Introduction to Human Evolution

Years ago millions of people died from smallpox, and their genes were not passed on because many of them died before reproductive age. When and why did we begin to walk upright?. Human evolution, the process by which human beings developed on Earth from now-extinct primates.

Viewed zoologically, we humans are Homo sapiens, a culture-bearing, upright-walking species that lives on the ground and very likely first evolved in Africa aboutyears ago.

Timeline of human evolution

The crucial turning point in human evolution, according to a theory published in by C. Owen Lovejoy, was the emergence of monogamy six million years ago. Until then, brutish alpha males who. human evolution, theory of the origins of the human species, Homo sapiens.

Modern understanding of human origins is derived largely from the findings of paleontology, anthropology, and genetics, and involves the process of natural selection (see Darwinism).

Human evolution. Human evolution is the lengthy process of change by which people originated from apelike ancestors. 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.
