What thereenviroment in different ways and is also

What is evolution? Evolution is thedevelopment of life on earth.

This process hasstarted billions of years ago and it’s still going on.It is the thing that made animals adapt to thereenviroment in different ways and is also thereason for the diversity of different species.DNADNA is the single most important prof thatevolution exists. It can be found in every livingcreature on earth without exeption.It’s located inthe cells of animals in the nucleous which containsthe chromosomes and they hold the DNA. DNA ismade up of different genes, they contain thecharacteristics and traits of living creatures.

Everycreature has it’s own mix of genes.DNA is also apretty big evidence that all of the creatures ofearth share a common ancestor. For exampleHumans and monkeys they share some similartraits such as the ability to walk on 2 legs, facialhair and a big brainvolume compared to th size ofthere body which suggests at some point the hadto have a common ancestor at which they startedto evolve on different paths.The discovery of evolutionCharles Darwin came up first with the theory ofevolution in the 1859 with his book: On the Originof Species . He came up with the idea that allspecies share a common ancestor.

Even though atthe time people didn’t know about DNA theyaccepted Darwin’s theory.DNA was firstdiscovered by Friedrich Meischer in 1869 and it’smolecular structure was discovered by JamesWatson and Francis Crick in 1953.Transitional FossilsThese fossils are used by scienticts to fill theevoulutional gaps between 2 spieces based oncommon traits. Although this isn’t a powerfullevidence of direct descent.Matching Traits to Common AncestorsScienticts can this to point out the differencesin species as they get further from the commonancestor and also to find the commoncharacteristics the remain tho both species.

Thisshows evolution in action, while also showing theways specialisation can occur. For example thesize and shape of the bodies of deer, moose,horses and zebras are very similar because theyhave a common ancestor from which they evolvedin minor but important ways.
