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. It is from the earlier life emergence up-to-date. The planet formed around 4.5 years. Life emerged before 3.7 billion years, as the evidence suggests. Some life evidence as first 4.1 to 4.28 years. This controversy is due to possible formations that were non-biological of the fossils purported. From the fossil records, it is indicating that they diverged through the evolution process from the same ancestor. About 1 trillion species live on the earth today and only 1.75 to 1.8 million species named. 1.6 are in the central-database.

The first evidence about life is from biogenic-carbon signature and the stromatolite fossils which were discovered .in the year 2015, biotic life remain were found about 4.1bilions years of age, in rock in Western-Australia. Microorganisms are the earliest forms of life known, and they left present signals in rocks around 3.7 billion years of age. Evidence of microbes(organisms) was also found in hard structure (stromatolite) dating 3.5 billion years. Macintyre. After cyanobacteria evolved around 2.4 billion years, a stage for remarkable transformation was formed. They were the first photo-synthesizer on the earth. Manufacturing food by the use of water, the sun’s energy, and oxygen was released as a result.

The evidence about the great-oxidation event is found in seafloor-rocks. Something happened revolutionary as microbes started living inside the others—mitochondria, which is an organelle that converts energy to energy evolved from the mutually-beneficial relationship. DNA, for the first time, became packed in nuclei. It later resulted in multicellular life. Custer of specialized cells became the first animal.

Question 2

The nucleus is the center of every atom. Breaking the core releases a large amount of energy. Modern nuclear-weapons operates by the combination of the chemical explosives, that the nuclear fusion and nuclear fission. This results in to release of massive power, which is usually x-rayed from and results to the highest pressure and temperature required for igniting fusion. During nuclear fission, split into lighter and smaller nuclei accompanied by energy release. Fusion works in the reverse if exposed to very high pressure and temperature. The atomic reactions have both potential and acute effects on health for human beings. For that reason, I think that society should deal with the invention to ensure that the reactions do not affect other human beings.
