Divergent evolution 1 The evolution of an ancestral species into an array of species that occupy diverse habitats is called radiation adaptive 2 Similar species unrelated organism evolve similar traits because they live in similar environments . BY JESSICA ROUT. THEORY OF . Evolution!. Darwin's theory of evolution. The basic idea behind the theory of evolution is that all the different species have evolved from simple life forms. These simple life forms first developed more than three billion years ago - the Earth is about 4.5 billion years old. The timeline below shows some of the key events in the evolution of life forms on Earth, from the first bacteria to the first modern humans.. ·Our anatomy resembles the anatomy of other animals.. ·.

A RESOURCE BROUGHT TO YOU BY THE GALAPAGOS CONSERVATION TRUST (REGISTERED CHARITY NO. 1043470). Introduction. Charles Darwin was a biologist who lived during the 1800s. Scientific thinking was shifting (biology & geology). Evolution = the process of change over time. Darwin developed a theory that explains how modern organisms evolved over long periods of time through descent from common ancestors.. &. 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!. 1.
