There are generally two types of heredity, namely, cultural and biological. Humans can accomplish cultural inheritance, unlike any other organisms. The cultural experience is cumulative that runs generation after generation. Let us discuss about the origin and the social and biological considerations of human cloning.
Origin of Humans
The lineage of humans originated from the chimpanzee lineage that evolved in the continents of Africa before Homo erectus origin. The human origin just after its emergence in the subtropical or tropical regions of Africa has gradually spread to the other continents of the world.
The transition phase from Homo erectus to Homo sapiens happened about 400,000 years before, though the exact dates cannot be determined due to various uncertainties and ambiguities. The fossils of the Homo sapiens were found around 200,000 years ago in Europe.
There are many controversies about the origins of the modern human race. Some anthropologists have the view that the human race came after the transformation from Homo erectus to Homo sapiens took place throughout the world.
The origin can be known by discovering the fossil and by comparing the living primates, comparing the proteins, DNA, and other molecules. The proteins and DNA can provide information on how we are related to each other with different primates.
Biological Evolution for the Modern Humans
There are scientific claims that sometimes biological evolution comes to the end of mankind. The concept of evolution will be clear after visiting MyBiosource.com. The genetic variation of mankind can be considered wealth in modern genetical science. There are exceptions when identical twins are produced from single-fertilized eggs, two people are never genetically identical and lived in the past, are living now, or will live in the future.
The stem cells or embryonic cells may have essential health applications with the help of therapeutic cloning. The injured nerve cells can be treated with the help of the transplantation of organs. Techniques like pluripotent stem cells and induced cloning, SCNT have been less costly and much more effective. The pluripotent stem cells have much potential for differentiating any of the germ layers of the features of animals and humans. Stem cells, just like pluripotent cells can be used for treating various diseases.
Stem cell therapy includes various embryonic cells for obtaining stem cells and other pluripotent cells that are used in treating different diseases with regenerative medicines. One of the effective applications of therapeutic cloning is organ growth by using stem cells with the genome of the recipient organ.
Social, Ethical, and Religious Cloning
When the person is allowed for cloning, social, ethical, and religious values will come into action. Many countries are not allowed human cloning. In 2004, the cloning issue was raised in various countries, and legislatures considered whether embryonic stem cells should be allowed or supported.
This article signifies the social, biological, and ethical considerations of human cloning in the future. It describes the human origin and the transmission from Homo erectus to the home sapiens in the primitive age. It also connects the modern human race and therapeutic human cloning with the social, ethical, biological, and religious considerations in human cloning.
