| Evolution |
| Evolution is the gradual change in any type of species over time. |
| Evolution was a theory started by Charles Darwin. Charles first saw that in Galapagos there were different types of Finches but with different types of beaks. He couldn't explain how they had changed but he imagined that the Finches must have started hunting in different parts of the islands for food. He saw that where Finches with beaks that look like Parot beaks, there were big nuts or fruts in that part of the island. So slowly through Natural selection the birds with bigger beaks that could get food would survive and the others would dye. The same with other Finches that went to another island were there were mostly flying insects and the birds with longer sharper beaks could catch the insects. These ofcourse would survive while others wouldn't. A nother way can be that some birds might have had the opposite beaks but some how some survived. Then they would pass small changes in their DNA to their offspring and the offspring might be born to look a little differentlly, but better adapt. |
| Pros and Cons about Evolution |
| PROS |
| CONS |
| 1. People have never found a fossil or a "missing link" between a human and an ape or a monkey. In other words people haven't found a person or a fossil of a species that were or was in between a human and an Ape. The "missing link". 2. Organisms don't evolve into more complicated things. They evolve into simpler things. 3. Where did Birds and Mammals come from. Once there were Dinasaurs, crocodiles, lizards, all reptiles. There were also spiders and insects, so where did Mammals and birds come from. There is no proof, no fossil or anything, that indicates that a reptile suddenly "transforms" or evolutions into a mammal or a Reptile. |

| 1. 97% of our genes are the same as those of the Apes. We are really close to them. Humans, Apes, Monkeys, Gorillas and Chimpanzees, all come from the same roots. Just that at some time we changed. We come closer to Apes than the others. There are diferences between us. We are more intelegent, we wlk straight and we have a better spoken Language. 2. Species must have evolutionized or else how come there are so many different species and how is it that under one species there are different types? We also have fossils that show how some animals changed over time. These fossils also prove to us that long ago there werent any mammals or birds and even before that there were only small organisms. 3. There is no way we could have survived if we wouldn't have evolutionized. At the begining of the world we know there wasn't much oxygen and there were a lot of volcanoes and lava. After that there were lots of oceans and then there was an atmosphere. After all these changes in the world tiny living organisms that lived in hot volcanic areas could not live in Oceans so they must have changed some way. |

| Human evolution |
| Human evolution took place over a time. The oldest skull of an ancient human is 200,000 years ago. It is certain that there was a race of primitive Humans that were called Neanderthals. These are the oldest humans. Then around 30,000 to 20,000 years ago a nother race of Humans started to enter the Neanderthals territory. These humans were called Eurasians. These people (according to one theory) came from aAfrica. (Back then the world was just a little different than Pangea. These humans started out living Neanderthals and the Neanderthals were eventually wiped out. The Eurasians started spreading all over the world slowly. The Eurasians were called homo erectus. This is the way humans developed. Australopithecus Aferensis. Out of thos the Australopithecus Africanus and the Parenthropus Aetheplicus. Both of these evolutionized into diferent roots, but e Parenthropus Aethiepicus' family died. After the Australopithecus Africanus, evolved 2 new families came out of it. The Homo Rudolfensis and the Homo Hobilis. The Momo Hobilis survived and out of it came out the Homo Ergaster and from Homo Ergaster came the Homo Erectus which did dye out but interbreeding must have happened with the other ones who were evolving. These became the HHomo Heidolbergonsis and out of them came out 2 other families. The Ho Homo Neanderthalsansis and the Homo Sapiens. The HomoSapiens survived and they evolved just a little bit to become what we are today. Homo Sapien Sapiens. |
