Question

write evolutionary history of modern man

Answer 1

Modern humans (Homo sapiens), the species? that we are, means ‘wise man’ in Latin. Our species is the only surviving species of the genus Homobut where we came from has been a topic of much debate. Modern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, Homo erectus, which means ‘upright man’ in Latin. Homo erectus is an extinct species of human that lived between 1.9 million and 135,000 years ago.

Historically, two key models have been put forward to explain the evolution?of Homo sapiens. These are the ‘out of Africa’ model and the ‘multi-regional’ model. The ‘out of Africa’ model is currently the most widely accepted model. It proposes that Homo sapiensevolved in Africa before migrating across the world.

On the other hand, the ‘multi-regional’ model proposes that the evolution of Homo sapiens took place in a number of places over a long period of time. The intermingling of the various populations eventually led to the single Homo sapiens species we see today.

Answer 2

Answer:

Here is your Answer

Explanation:

The Hominidae or great apes, that ultimately evolved into the modern human being, evolved about 7 million years ago.  

Around 2.5 million years later, the Ardipithecus ramidus, which could both live on trees, as well as walk about on land, roamed the earth.  

Further evolution took place over the next 1.5 million years, which brought forth the Australopithecus afarensis.  

Another half million years later, came the Homo Habilis, the Homo Erectus and the Homo Heidelbergensis. The modern man or Homo Sapiens are thought to have evolved about 2 - 3 million years ago in Africa.
