Evolution

I watched a PBS series called Evolution. This was a series of seven videos discussing many different aspects of evolution. It captures with defining what a theory is and encompasses. It essentially explains the basic beginnings of how people smacked at evolution, and about oft about Charles Darwin and his inferences that all living creatures, including humans, descended from a color ascendent. He said, Each new species is a new chute that springs from the parent tree. These new chutes branch out and develop in their turn and so on, about branches die out and some keep developing, the trunk being the ancient common ancestor. This basically describes his theory in terms easy for the audience to understand. The videos thus go on to speak about the evidence we strike to prove evolution has taken place. Fossils are the biggest way they ensnare do this. It starts with whale fossils. It shows the many similarities we direct to whales, raising the query mood; how di d the shift of evolution happen from life on overturn to life in the water? Scientists then begin to look at various whale fossils and conclude that whales evolved from a reach mammal called Sinonyx. Over millions of years the front legs became fins and bodies alienated fur and began to take on the stream line building they grant for swimming.

It then began to speak more in depth of the header of if humans evolved. It said that we didnt evolve from chimpanzees nevertheless twain humans and chimpanzees adjudge a similar mental synthesis to the alike(p) ancestor. Also, it tells about how DNA can help determine how more or less related we are to another species, which would be the chimps, and then linking us to the same com! mon ancestor, which would be apes. Scientists then prove that we have 98% similarities with a chimp, but some(prenominal) less with a rat, even though we have a common ancestor with the rat as well. The reason our DNA similarities are much less is because the common ancestor lived much longer ago than our common ancestor with the chimp. The videos then...If you want to get a tidy essay, order it on our website: OrderEssay.net
