Homologous structures is an example of science as a life process. Homologous structures are structures that evolved from a common ancestor for a similar purpose but do not perform the same function. An example of this is the exact replica of the original bone in the forelimb of humans, cats, bats, and porpoises. The bone in each of these animals does nto loof or operate the same but has come from a common ancestor.

Evolution: Origins Of Life.
Many theories have been studied to answer the origin of life.
The Miller-Urey experiment stimulated the conditions on earth at the ideal time of orgainism develipment. The model produced orgainic compounds and amino acids.
Other experiments included:
Fox's Theory: spontaneous formation of peptide structures
Clay Theory: complex organic molecules arose gradually on a pre-existing, non-organic replication platform
