The history of life here on the earth
The history of life here on the earth tries to trace the processes whereby the fossils and the living organisms evolved. This is from the earlier life emergence up-to-date . the earth formed around 4.5 years. Life emerged prior to 3.7 billions years as the evidence suggests. some life evidence as early 4.1 to 4.28 years. This controversial is due to possible formations which were non-biological of the fossils perported. From the fossil records ,it is indicates that they diverged through evolution process from same ancestor. About 1 trillion species live on the earth today and only 1.75 to 1.8 million of species named. 1.6 are in the central-database.
The first evidence about life are from biogenic-carbon signature and the stramatolite fossils which were discovered .in the year 2015 biotic life remain were fpund about 4.1bilions years of age, in rock in western-australia. Microoranisms are the ealiest forms of life known and they left present signals in rocks around 3.7 bililion years of age. Evidence of microbes( microorganisms) were also found in hard structure ( stromatolite) dating 3.5 billions years . maclntyre.after cyanobacteria evolved around 2.4 billion years, a stage for remarkable tranformation was formed. They were the first photo-synthesizer on the earth. Manufucturing food by use of water, sun’s energy and oxygen was released as a result.
The evidence about great-oxidation event is found in seafloor-rocks. Something happened revolutionary as microbes started living inside the others. Mitochondria which is an orgalelles which converts energy to energy evolved from the mutually-beneficial relationship.DNA for the first time became packed in nuclei. This later resulted to multicellular life. Custer of specialised cells became the first animal.
Nucleus is the center of every atom. Breaking the nucleus releases large-amount of energy.modern nuclear-weapons operates by the combination of the chemical explosives, that the nuclear fusion and nuclear fission. This results to release of massive energy which are normally x-rays form and results to the highest pressure and temperature required to for igniting fusion. During fission nuclear split into lighter and smaller nuclei accompanied with energy release. Fusion work the reverse if exposed to very high pressure and tmperature.nuar
