Write short note on human evolution of 10th
Answers
Answer:
There is a great diversity of human forms and features across the planet. The tools used to trace evolutionary relationships have also been used for studying human evolution. For ex. excavating, time dating, studying fossils and determining DNA sequences. Shin colour used to be the commonest way for identifying the races due to the diversified forms of human and their features. However, there is no biological basis to the motion of human races. All humans are of single species. The earliest member of the human species, homo sapiens can be traced in Africa.
Question
Write short note on human evolution
Answer
The evolution of man is something which has been debated for years and will be for many years to come. Modern man scientifically called Homo sapiens has evolved as years passed down the line. It all began from Ramapithecus which were existing 15 millions years ago(Mya) . They were probably not taller than 4 feet but walked upright . Then 2 Mya there came Australopithecus who lived in East African Grasslands. They hunted for food with stone weapons but mainly ate fruits.
The first Human like being was Homo habilis . Their brain capacities were 650–800cc. They didn't eat meat. Next came the Homo erectus who had a large brain if around 900cc. They ate meat. The Neanderthal man with brain size of 1400cc lived 1 lakh to 40 thousand years ago. They used hides to cover their body and buried their dead. Homo sapiens arose in Africa and got distributed throughout the globe. Agriculture came around 10 thousand years ago. The rest what happened is history.
