| Statement of the theory is {Evolution of organisms depends mainly on gene evolution through the appearance of novel genes. Diversity of Living organisms results from genetic variations. Each Individual in the same species of Living Organisms has its own Identity of DNA Finger-print. Variations of Individuals Results from Effect of Environmental Factors, Mutation and Invader of Genetic Materials}. Gene evolution depends mainly on gene duplication ,variation of environmental conditions, mutation, transposable elements, horizontal gene transfer (HGT),de nove gene that originated from non-coding DNA which mainly comes from retrovirus and micro-RNA. And invader nucleic acids from viruses, bacteria or any parasite.The main prediction of this theory is not only each individual of human being has unique DNA fingerprint, but also any individual in the same species has also unique identity in DNA fingerprint. Any living organisms acquire genetic materials through its intimate contacts with another organisms . If the acquired genetic material reach to germ cells, it could transfer to next generation giving new traits.Viruses considered the main source for genetic transformation in all living organisms. The genomic materials of some viruses could integrate inside human genome like hepatitis B and HIV. The human genome has about 5 % virus genetic material especially from retroviruses.This theory could explain the appearance of new individuals according to transfer of genetic materials during intimate contact between different species, and support many researchers who discovered new species. Also ,this theory explain and will answer different questions , why husband and wife after some time, nearly acquire some similarities ?, why people in the same geographical area nearly have a similar pattern ?. The answer on this questions is return to the transfer of micro RNA which found in food, fluids and environment that surround the organisms. Also, similarity may return to transfer of transposable elements through intimate contacts within individuals . This theory also, explain the host-parasite relationship depending through transfer of DNA and RNA between them. We developed in our lab. Simple technique for detection of DNA and RNA from tissue lysate, through it micro- RNA could be detected. We detected the instability and dynamicity of DNA through sister chromatide exchange (SCE). Also we detect individual variation in the same species through haplotype analysis, this support our theory. | ||||
