Explanation:
Evolution is a slow natural process occurring in living organisms which explains the formation of the diversity of organisms on Earth. In simple terms, evolution explains how life survived on Earth after the origin of life but it cannot explain the origin of life. However, modern evolutionary biologists are now trying to decode the origin of life through evolutionary evidence and support that earlier form of life originated in the large oceans around 3.5 billion years ago. These organisms are simple living unicellular organisms which later evolved into the eukaryotic organisms.
The limiting factors of an ecosystem are Habitat, Space, Resource abundance, or the reproductions<span />
Therapeutic cloning<span>generates personalized ES cells
o Uses the technique of nuclear transplantation to produce cultured ES cells
o The cell that has received the transplanted nucleus is allowed to undergo the earliest steps of development giving rise to a very early embryo consisting of about 200 cells
• Not transferred into the uterus of a foster mother but used as a source from which ES cells are derived
o Cells obtained are genetically identical to the original donor
• Can be grafted back into the adult from whom the donor tissue was taken without fear of immunological rejection</span>
