Members: Goh Zhi Hwee See Yong Chun Ryan Lau Meng Fanbo Survival of the fittest Evolution Vs. R-Evolution It is not the strongest of the species that survives, nor the most intelligent, it is the one that is most adaptable to change ~Charles Darwin

How it came about What is Natural Selection Misconceptions of Natural Selection How is it perceived as revolution How + why is it widely regarded as an Evolution Evolution Vs. (R)evolution Purpose of Natural Selection Extinction (role)

Charles Darwin

What? It determines which species form the majority of the population Basically a natural breeding selection Many different species living in a particular environment Adaptation affects survival rates If survives Genes will be passed down to the offspring Adaptability will be improved Evolution happens (constant) More suited to the particular environment

Natural Selection is a process and not a guide Results from Variation Differential reproduction Ability to produce more offspring with same adaptation as the parents Ensure continuity of the species when conditions change Heredity Natural Selection does not supply what an organism needs Selects among whatever variations exist in the population Evolution Natural Selection is not random Genetic variants that aid survival and reproduction More common than variants that do not

How? Possible due to drastic changes Modifies the structure of the ecosystem Changing the fundamentals of the ecosystem structure ∴ perceived as Revolution

How + Why? Perceived as an evolution as in both Evolution and Natural Selection Animals develop and evolve due to possible genetic mutations Constant improvement in genetic traits of animals to survive + adapt ∴ perceived as Evolution

Revolution Fundamental change in power or organization structures Evolution General change in genetic characteristics passed down many generations Mainly for adaptation in species Revolution Focus the change in populations of 2 different species, with one dominating over the other Evolution Refers to same species of animals Developing mutations Become more adapted to its environment Revolution Focus the change in populations of 2 different species, with one dominating over the other Evolution Refers to same species of animals Developing mutations Become more adapted to its environment

Is? Natural selection Modifies an ecosystem To be self-sustaining Develop species with the suitable traits for proper survival in a particular environment Prevents Species with undesired traits Be easily hunted and turn extinct Allow species with proper traits to survive
