The human evolution history

  THE HUMAN EVOLUTION 

The biodiversity that is known today has been said to be formed from very ap unicellular organisms due to evolution. In this evolution, origin of human evolution can be shown as per the picture given below Last dinosaurs disappeared approximately seven crore years ago. At that time, monkey-like animals are said to be evolved from ancestors who were more or less similar to the modern lemurs Tail of these monkey-like animals of Africa is said to be disappeared about 4 crore years ago. They developed due in enlargement in brain their hands were also improved and thus ape-Itike animals were evolved Meanwhile, these ape-like animals reached the South and North-East Asia and finally evolved into gibbon and orang-utan.


Remaining ope-like animals stayed in Africa and from them, gorilla and chimpanzee evolved about 2.5 crore years ago Evolution of some of the 2 crore year old species of apes seems to be occurred in different way. They had to use their hands more for oating food and other work.


Those apes started to live on land as the forests started to decline due to dry environment Their lumbar bones developed in such a way that they started to stand in erect posture in grasslands and thereby their hands became available for use, anytime. These first bus -like animals with crect posture which were using their hands have evolved about 2 crore years ago.


First record of human-like animal is with us in the form of "Ramapithecus ape from East Africa. Afterwards, this ape grown up in size and become more intelligent and thus the ape of South Africa evolved about 40 lakh years ago.

HEREDITY

  Heredity and hereditary changes  You know that heredity is the transfer of biological characters  from one generation to another via Gene's.  Johann Gregory mendel is pioneer of the modern genetics. Around the period of 1886 ,it took a long time for him to understand the conclusions of his research about heredity. In 1901,the reason behind the sudden changes were understood due to the mutational theory of hugo de vies. Meanwhile in 1902 ,Walter and sutton observed the paired chromosomes in the cells of grasshopper; until then it was not known to anyone.Research started in the direction of finding the nature of genetic material when it was proved that genes are carried via chromosomes. Through which 1944,trio of scientists Ostwald  avery ,Mclyn mc cathy and colin MacLeod proved that except viruses ,all living organisms have DNA as genetic material.  In 1961,the French geneticists Francois Jacob and Jack monald proposed a model for process  of protein ...
