Cloning: Taking unfertilised egg and removing nucleus. Nucleus also removed from adult body cell and inserted into empty egg cell. Egg cell stimulated with electric shock -> makes it divide. When embryo is ball of cells - implanted into womb and grow

... are remains of organisms from thousands of years ago found in rocks. They provide evidence. They show evolution's but not the first life
Fossils

Different ... of fossils: 1) Parts that don't decay easily are replaced by minerals, forming a rock like substance. 2) Casts and impressions where animal decays in soft material which eventually hardens 3) Preservation where no decay happens

A species is a group of similar organisms that can produce fertile offspring. ... is the development of a new species which occurs when species can't produce fertile offspring
Speciation
5 of 11
... separates species e.g. a physical barrier. Conditions on both sides will be different, as the environment is different, natural selection occurs and the populations get different characteristics
Isolation

... worked on the idea of speciation. He came up with the idea of natural selection. His evidence supports the theory of evolution by natural selection. Most famous for speciation and finding out about animal warning colours to deter predators

... grouped organisms according to their characteristics and structures. In the system, living things divided into Kingdoms, and then smaller groups -> Phylum, Class, Order, Family, Genus and Species
Carl Linnaeus

With technological advances, new models of ... were put forwards: Carl Woese proposed 3 domain system -> Archaea- Primitive bacteria found in extreme places. Bacteria - true bacteria e.g. E-coli. Eukaryota- Broad range of organisms
Classification

Organisms are named according to the ... : Every organism is given its own 2 part Latin name. First part refers to genus and second part refers to species. System is used worldwide so all countries can talk about the same thing. Humans = Homosapians
