The process of evolution has four forces‚ mutation‚ gene flow‚ genetic drift‚ and natural selection. Evolution is caused by the isolation of populations which leads to variation and eventually speciation. A population is a group of individuals within

Evolution of land animals THE LARGEST genetic study ever performed to learn when land plants and fungi first appeared on the Earth has revealed a plausible biological cause for two major climate events: the Snowball Earth eras‚ when ice periodically covered the globe‚ and the era called the Cambrian Explosion‚ which produced the first fossils of almost all major categories of animals living today.
