These birds are all members of the same species What variations can you see among them 12 What are resources for these birds The Birds Environment lots of bushes and trees some with . Evolution. Results of evolution. New species (speciation). Causes of evolution. Barriers between same species (gene pools). Geographical isolation -> leads to . allopatric. speciation. Temporal isolation -> leads to sympatric speciation. &. Evolution. By. Hayden. &. Elijah the awesome . How do species evolve. All species are related to each other. If you trace your family tree back through your parents, grandparents etc. it will quite quickly join up with your cousin’s family tree. If you keep going back far enough, eventually your tree will join up with that of a chimpanzee! Keep going and it will join up with your pet hamsters, further still with your pet cats. Keep going and eventually it will join up with your pet goldfish and if you really keep going for a long time you can trace it back so it joins up with an apple tree’s family tree, and eventually bacteria will join up too!. Born in England in 1809. Enrolled in divinity school at Cambridge; graduated in 1831. In 1831, Darwin signed on the naturalist on the HMS Beagle & traveled around the world for the next 5 years. He gathered data during his travel; that data was used as the basis for his books and ideas on evolution. 1. Blood . proteins in horses are chemically similar to blood proteins in monkeys.

The evolution of life is linked to the physical and chemical evolution of the earth.. Life on earth evolved in two phases over the past 4.7 -4.8 billion years. Chemical evolution (1 billion years) of the organic molecules and systems of chemical reactions needed to form the first proto-cells..
