Evolution

I watched a PBS series called Evolution. This was a series of seven videos discussing many different aspects of evolution. It cast downs with defining what a theory is and encompasses. It essentially explains the basic beginnings of how people smacked at evolution, and pulse oft about Charles Darwin and his inferences that all living creatures, including humans, descended from a honey oil ascendent. He said, Each new species is a new parachute that springs from the parent tree. These new chutes branch out and develop in their turn and so on, nigh branches die out and some keep developing, the trunk being the ancient common theme. This basically describes his theory in terms easy for the audience to understand. The videos thusly go on to speak about the evidence we don to prove evolution has taken place. Fossils are the biggest way they ready do this. It starts with whale fossils. It shows the many similarities we direct to whales, raising the doubtfulness moo d; 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 garbled fur and began to take on the stream line organize they grant for swimming.

It then began to speak more in reason of the header of if humans evolved. It said that we didnt evolve from chimpanzees just twain humans and chimpanzees get under ones skin a similar social system 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 wo uld be the chimps, and then linking us to th! e same common ancestor, which would be apes. Scientists then prove that we have 98% similarities with a chimp, but ofttimes 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 agone than our common ancestor with the chimp.
