LIFE
What is life?.Have any one of us thought about it. Can any one us knows about it.Is life is what we see today. Life is a characteristic distinguishing objects having signalling and self-sustaining processes from those that do not,either because such functions have ceased (death), or because they lack such functions and are classified as inanimate.This are we word that i have got while checking in Internet.Life is a study concerned with science of biology.An organism is any contiguous living system.Organisms undergo metabolism, maintain homeostasis, can grow, respond to stimuli, reproduce and, through natural selection, adapt to their environment in successive generations. More complex organisms can communicate through alternative means.A diverse array of living organisms can be found in the biosphere of Earth, and the properties common to these organisms—plants, animals, fungi, protests, Archer, and bacteria—are a carbon- and water-based cellular form with complex organisation and heritable genetic information.
The Earth was formed about 4.54 billion years ago. The earliest life on Earth existed at least 3.5 billion years ago,during the Archean Era when sufficient crust had solidified following the molten Ha dean Eon. The earliest physical evidence for life on Earth is bionic graphite in 3.7 billion-year-old meta sedimentary rocks discovered in Western Greenland and microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia.Nevertheless, several studies suggest that life on Earth may have started even earlier, as early as 4.25 billion years ago according to one study, and even earlier yet, 4.4 billion years ago, according to another study. The mechanism by which life began on Earth is unknown, although many hypotheses have been formulated. Since emerging, life has evolved into a variety of forms, which biologists have classified into a hierarchy of tax's. Life can survive and thrive in a wide range of conditions.Actually this are the words that i have got while researching the information.Ever humans want there life and there families life to be safe they ever doesn't considers other life or even does not think about them.Also life is also a mixture of happy,sadness,sorrow etc.Every humans must also posses this situations in there life.No humans in this world are always happy every person has some sorrow or sadness in life.so life is a mixture of happiness,sadness,sorrow etc.
Evolution
What is a Evolution?.The change in the inherited characteristics of biological population over a a lot successive generation is the Evolution.The diversity at every level of biological organisations,like species,individual organisms and molecules like proteins and DNA is the evolutionary processes.Approximately 3.8 billion years ago All Life On Earth is descended from a last universal ancestor.By the from shared set of biochemical and morphological traits,or else by the DNA sequences that has been shared from the repeated specification and the divergence of the life can be inferred.Those the homologous traits and sequences are more similar among the species that share a more recent same ancestor,and may be used for tore construct evolutionary histories,by the use of both the fossil record and the existing species .Speciation and by the extinction are been shaped by the existing patterns of biodiversity.A scientific argument for the theory of evolution by the means of natural selection was first made by the Charles Darwin.
In the Darwin's theory of evolution by natural selection through the discipline of population genetics early 20th century,genetic was also integrated with Darwin's theory.It was accepted into other branches of biology because of the importance of natural selections because of the as a cause of evolution.Scientists continue to study various aspects of evolution by forming and testing hypotheses, constructing scientific theories, using observational data, and performing experiments in both the field and the laboratory.The most reliably established facts in science is the descent with modification it was also agreed by the biologists.The discoveries in evolutionary biology have made a significant impact not only one the traditional branches of biology,and also in the other academic disciplines and on society at large.
