Document Summary
Decent with modification: a darwinian view of life. Evolution: charles darwin published the first convincing case of evolution in 1859, evolution: the transformation of the lifeforms on earth over time. What kind of change is happening: a change in the frequency of the alleles of a population (note: an allele is a gene for a specific trait) Mutation which favors one allele over another. Mutation which creates a new allele that is favored. How much time: several generations for the organism. For bacteria a day or two could be plenty of time to see changes. For humans may be 200-300 years before change can be seen. Most are spotted in around the 1000 year mark: darwin"s ideas were opposed by western philosophy. States that all species were created exactly as they exist today. Most popular hypothesis for the origin of species according to western philosophy. May be strictly biblical or may involve continual creation.
