Document Summary

Transmutation of species (changing of species, over time. ) The idea that the earth is older than it seems, tried to figure this out. Inheritance of traits, these traits will be passed down to offspring giving a change getting passed to the next generation. Lamarck didn"t know that somatic cell didn"t go under meiosis, it"s the germ cells that do. He didn"t understand somatic cells are not the genetic information. Infusatoruim beginning of traits as time goes on it gets more complex. Transmutation of the essence (not lamarck very different) rapid change in the essence. Finalism essence has a preprogramed and will happen over time. Environmental (not lamarck) environment have no effect on change. Saw that different species from island to island. Voyage of the hms beagle (collects a bunch of samples after every spots and collected a biodiversity) Theory of a branching pattern survival of the fittest pass on traits to next generation.
