who study the course of early human evolutionary history

Full Answer

What is the history of human evolution?

See Article History. 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 about 315,000 years ago.

How do archeologists study the process of evolution?

By studying this type of evidence, archeologists can understand how early humans made and used tools and lived in their environments. The process of evolution involves a series of natural changes that cause species (populations of different organisms) to arise, adapt to the environment, and become extinct.

What is the evidence for human evolution?

Human evolution took place as new genetic variations in early ancestor populations favored new abilities to adapt to environmental change and so altered the human way of life. Dr. Rick Potts provides a video short introduction to some of the evidence for human evolution, in the form of fossils and artifacts.

Why do some people find the concept of human evolution troubling?

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.

When did humans evolve?

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 about 315,000 years ago.

What is the primary resource for detailing the path of human evolution?

The primary resource for detailing the path of human evolution will always be fossil specimens. Certainly, the trove of fossils from Africa and Eurasia indicates that, unlike today, more than one species of our family has lived at the same time for most of human history.

When was the Homo sapiens first discovered?

The oldest known remains of Homo sapiens —a collection of skull fragments, a complete jawbone, and stone tools—date to about 315,000 years ago. Homo sapiens.

What is the name of the first human ancestor?

More recent human ancestors belong to our same genus - Homo - indicating a closer genetic relationship. The first known member of our genus was Homo habilis. This ancestor lived 1.6-2.4 million years ago and was called 'handy-man' because of the evidence of advanced tool use.

When did hominoids first appear?

The hominoids, a group of primates including gibbons, orangutans, gorillas, chimpanzees, bonobos, and humans, began to evolve from an Old World ancestor about 20-25 million years ago .

What are the differences between humans and other primates?

Other notable differences between humans and other primates are that humans have drastically smaller jaw bones and jaw muscles due to differences in dietary habits. Humans also have shorter digestive tracts than other primates because of the food that we eat.

How old are hominins?

Hominins are hominoids that are related to humans. The oldest distinct hominin is around 6-7 million years old. We won't look at all of these human ancestors but will rather highlight a few distinctive species. Let's first look at Australopithecus.

Where do the Old World and New World primates live?

Old World primates live in Asia and Africa, while New World primates live in South America. The hominoids evolved from Old World primates and include humans, gibbons, and chimpanzees. Humans are different from other primates in that we: Walk on two feet rather than four. Are capable of language and symbolic thought.

Where did primates originate?

Our ancestors originated in Africa and then migrated elsewhere around 50,000 years ago. Scientists have specifically studied mutations on the Y chromosome - which all males have - to trace the migration out of Africa and into other specific areas of the world. Lesson Summary. Primates are mammals with:

Where did the first primates live?

The earliest primates lived in trees. They used their hands and feet - both capable of grasping - to move between and among trees using the branches and vines. Some also had tails to help maintain balance. A living organism that most closely resembles these early primates is the lemur. These early primates separated into two groups with distinctively different patterns of evolution. The Old World primates reside in Africa and Asia, while the New World primates reside in South America.

When did Homo sapiens first appear?

September 23, 2015. Recent discoveries have provided much new information on the emergence and spread of modern humans. [1] . Scholars in the field of genetics have established that Homo sapiens originated in Africa in about 200,000 B.P., and that our species subsequently displaced all previous hominid species.

What did Homo sapiens learn from the grasslands?

Early communities of Homo sapiens, at each stage of developing technologies and exploring new ecologies, found new ways to benefit from life in the grasslands and also from life at water’s edge. Studies of human evolution have long tended to emphasize hunting and the grasslands.

How to find the homeland of a Romance language?

To estimate the homeland for the ancestor to Romance languages: (1) on the map, locate and mark the point that is the geographical center for each Romance language; and (2) locate the point that minimizes the total distance from it to each of these points.

When did humans migrate to the Pacific?

The two final sections apply this global combination of methods to address, chronologically, the tropical migration of humans from Africa to the Pacific in the era from about 80,000 to 50,000 B.P. and then the human occupation of the temperate Old World and the Americas from about 40,000 to 30,000 B.P.

Where did humans move from the tropics to Eurasia?

Thereafter, the analysis considers four possible routes by which humans might have moved from the tropics into temperate zones of Eurasia, and concludes that the easternmost route, along the eastern coast of Asia, is attested most clearly by linguistic evidence.

Where did Homo sapiens migrate?

In this colonization of new lands, Homo sapiens migrated east along the tropical lands bordering the Indian Ocean. This tropical migration appears to have stemmed from the development of new technologies and social systems, allowing humans to occupy a steadily wider range of ecologies.

When did humans move to the Mediterranean?

In their first migration out of Africa, modern humans moved into the region east of the Mediterranean as early as 100,000 B.P. The archaeological record shows that there were alternations of modern humans and Neanderthals in the region, even in the occupation of individual caves, and that Neanderthals continued to live in the area until about 40,000 B.P. [44] For modern Homo sapiens, this was an early but limited movement out of Africa, which left no linguistic remains and for which the population did not become sizeable. Desiccation of the Sahara in the period from 90,000 B.P. suggests reasons why this northern region might not have remained hospitable to humans.
