- 1.AQA GCSE INHERITANCE VARIATION AND EVOLUTION PART 4 Evidence from around the world, experimentation, geology, fossils, discussion with other scientists (Alfred Wallace) lead to: Theory of evolution (Biology only) Other theories e.g. Lamarckism are based on the idea that changes occur in an organism during its lifetime which can be inherited. We now know that in the vast majority of cases this cannot occur. Developed since its proposal from information gathered by other scientists. Speciation (Biology only) Did much pioneering work on speciation but more evidence over time has lead to our current understanding. Allows biologists to understand the diversity of species on the planet. The understanding of genetics (biology only) Led to gene theory being developed but not until long after Mendel died. Evidence for evolution Fossils and antibiotic resistance in bacteria provide evidence for evolution. Early forms of life were soft bodied and few traces are left behind and have been destroyed by geological activity, cannot be certain about how life began. Fossils tell scientists how much or how little different organisms have changed over time. Evolution is widely accepted. Evidence is now available as it has been shown that characteristics are passed on to offspring in genes. Classification of living organisms Organisms are named by the binomial system of genus and species. Humans are Homo sapiens The full human classification Due to improvements in microscopes, and the understanding of biochemical processes, new models of classification were proposed.
