The process by which organism change over time Based on science not opinion Darwin Evolution is descent with modification Evolution changes through time Species accumulate difference. Theistic Evolution. God used method of evolution to make all living things . Some Christians - Genesis is a mythological account . Other Christians . - each day is billions . of . years. Earth is ancient – about 10 billion years old. Scientific Theory. Social use of the word “theory”. Not the same as in science. Implies a hunch or a casual guess. Scientific Theory. 1.

How do scientists account for the development of life on earth?. What is biological evolution by natural selection, and how can it account for the current diversity of organisms on the earth?. Artificial selection increases life span in fruit flies. Inherent limits, or can lifespan evolve?. Fruit fly expt:. Female sockeye salmon defending its nest before dying. II. Fundamental Trade-offs. Mite Kiwi bird. Evidence from around the world, experimentation, geology, fossils, discussion with other scientists (Alfred Wallace) lead to:. Theory of evolution . (Biology only). Charles.
