We are told that evolution is a continuing phenomenon for all living things. Are humans also evolving ? Justify your answer.
Solution
Yes, human is also evolving. Fossils give the evidences that evolution is a continuous phenomenon.
Our ancestors like Ramapithecus, Australopithecus, Homo habilis, Homo erectus, Neanderthal man and Cro-magnon man continuously evolving and modem man (Homo sapiens sapiens) arises from certain modifications. About $15 \mathrm{mya}$ Dryopithecus and Ramapithecus were existing. They were hairy and walked like gorillas and chimpanzees. Ramapithecus was more man-like while Dryopithecus was more ape like.
2mya Australopithecines probably lived East African grasslands, they ate fruits. They have ape like characters like-small stature, large incisors,supraorbital ridges and chinless. They have man like characters like-erctposture, bipedal, lumbar curve etc. Homo habilis is the first human -like being the Hominid.
The brain capacity of him were between $650-800 \mathrm{cc}$. They probably did not eat meat. They showed Bipedal, erect posture. They are first tool maker(Handy man). Fossils discoveredin Java in $1891$ revealed next stage i.e Homo erectus about $1.5 \mathrm{mya}$. They had large brain and $900 \mathrm{cc}$. They probably ate meat. They first used fire. They were chinless.
Neanderthal man is with brain capacity $1400 \mathrm{cc}$. They lived near east and central Asia between $1,00,000$ $40,000$ years back. They used hides to protect their body and buried their dead. They were cave dwellers. Homo sapiens arose $75,000-10,000$ years ago during ice age. Pe-historic cave art developed about $18,000$ years ago. They have flat forhead,chin is present,no supra-orbital ridge erect posture. So we can say that evolution is continuing phenomenon even in man.
