Document Summary
His observations of living and fossil animals convinced him that plants/animals change slowly through time (which is key to understanding new species) The ability of a population to expand is infinite, but the ability of the environment to support these populations is finite. Variation transmitted from parents to offspring: the inheritance of variation. Grant finch experiment in the galapagos island displayed darwin"s theory o . The larger and deeper the beak of the finch, the greater chance of survival as the ability to eat larger size seeds occurs. Stabilizing selection process that produces equilibrium in natural selection. Many of darwin"s contemporaries were convinced that new species. In darwin"s time, most adaptation was continuous (ie; height) arrived as discontinuous variants (not of norm in the continuous expectation) Australia) o selection producing some big changes in short periods of time. Complex changes take longer to evolve, but some evidence shows.
