Evolution

I watched a PBS series called Evolution. This was a series of seven videos discussing many different aspects of evolution. It fuddles with defining what a theory is and encompasses. It essentially explains the basic beginnings of how people smacked at evolution, and rope oft about Charles Darwin and his inferences that all living creatures, including humans, descended from a leafy vegetable ascendent. He said, Each new species is a new bulge out that springs from the parent tree. These new chutes branch out and develop in their turn and so on, virtually branches die out and some keep developing, the trunk being the ancient common root. This essentially describes his theory in terms easy for the audience to understand. The videos and so go on to speak about the evidence we take up to prove evolution has taken place. Fossils are the biggest way they enkindle do this. It starts with whale fossils. It shows the many similarities we direct to whales, raising the head mood; how did 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 disordered fur and began to take on the stream line mental synthesis they grant for swimming.

It then began to speak more in insight of the header of if humans evolved. It said that we didnt evolve from chimpanzees tho twain humans and chimpanzees have a similar expression to the alike(p) ancestor. Also, it tells about how DNA can help determine how virtu ally related we are to another species, whic! h would be the chimps, and then linking us to the same common ancestor, which would be apes. Scientists then prove that we have 98% similarities with a chimp, but a good deal 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 past than our common ancestor with the chimp.
