How did life originate? Living things (even ancient organisms like bacteria) are enormously complex. However, all this complexity did not leap fully-formed from the primordial soup. Instead life almost certainly originated in a series of small steps, each building upon the complexity that evolved previously:

Topic: Ecosystems | CosmoLearning Biology Ecosystem is the complex of living organisms, their physical environment, and all their interrelationships in a particular unit of space. An ecosystem can be categorized into its abiotic constituents, including minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consisting of all its living members. Linking these constituents together are two major forces: the flow of energy through the ecosystem, and the cycling of nutrients within the ecosystem. The fundamental source of energy in almost all ecosystems is radiant energy from the sun. The energy of sunlight is used by the ecosystem’s autotrophic, or self-sustaining, organisms.
Biological evolution is one of the three most profound discoveries in science. The other two are the vastness of the universe and geologic time. As such, biological evolution, along with the other two, deserves to be the foundation of all science learning, and should be taught from an early age. If the typical fourth grader can name planets in their order from the sun, she should also know that life is all related by descent from common ancestors. Life on Earth is One Big Extended Family.
