Evolution is the main
Different theories for evolution
Darwin’s theory
He came up with the idea of natural selection e.g. survival of the fittest(Individuals that have characteristics that make them more adapted to the environment which make them have a higher chance of survival are more likely to breed successfully)
Evolution can occur due to mutations
A mutation is a change in an organisms DNA. Most of the time it has no effect but sometimes in has a positive affect by producing a characteristic which gives the organism a better chance of surviving and reproducing. Over time the beneficial mutation will accumulate in a population.
Disagreements on Darwin’s theory-
· Religious beliefs It was the first explanation for our existence without a need of god
· She couldn’t give a good a good explanation for this
· There was no evidence to convince many evidence
Lamarck’s Theory
Argued that if a characteristic was used a lot by an organism than it would come more developed over time. He also believed that acquired characteristics would be passed to the next generation.
