Explanation / Answer

1. Human evolution has always been a topic of much debate and speculation with numerous theories provided by well known researchers, but each having its areas of doubts and missing links. I find this topic very interesting and intriguing as no definite theory has been propounded which is accepted by all and can provide scientific explanations to the origin of so much diversity in the Homo sapiens, the name we have given to ourselves. Just when the scientists had begun to agree on the theory that humans evolved in Africa, newly discovered human-like footprints in Crete and the ' ancient head ' out of China, upset the very base of the different theories. A deep look into the topic would definitely widen my horizon and knowledge of this topic.

2. Human Evolution is a topic which is still open to exploration and research. It is something for which, we have to depend heavily on fossil records and remains of skeletons which point to even a remote similarity with the modern day humans. Since ther is no written record and the wholle process of human evolution has taken millions and millions of years, to get an exact sequence of the evolutionary process can only be theorised. Researcher and anthropologists have done their best to provide the closest and scientifically correct sequence of events but still there are loopholles for which no solid explanation can be provided.

Discovery of millions of stone tools, figurines, paintings etc give us a peep into the behaviour and lifestyle of pre-historic humans, Study of human genetics help us to establish how closely we are related to other primates. It also helps to trace the pre-historic migration of our species all over the world. Advances in the dating of fossils and the artefacts used by prehistoric man has helped archeologists to determine the age of such remains . This has helped creat a bigger picture of when different milestones were achieved in the long and slow journey of human evolution.

3. What was most surprising was that modern humans, Homo sapiens, and Neanderthals,Homo neanderthalis , have 1 to 4% more in common between the genomes of non-African humans and Neanderthals than with the subsaharan Africans. Modern humans and Neanderthals share genes for lactose intolerence and also a gene variant associated with brain development and speech. This ,according to researchers indicates that Neanderthals might have been able to speak. This sounds amazing !
