Lecture 13: darwin"s big idea and how it changed biology. Living things change gradually from one from into another over time. Concept of a changing universe (constantly changing) v replaced view of a static world. Propose a causal mechanism the inheritance of acquired characters (wrong!) The giraffe"s neck: lamarck"s example for the inheritance of acquired characters. Linear evolution (wrong because evolution is actually branched) (cid:159) Progressive increase in neck during the life time of individuals is passed on to offspring. (cid:159) wrong because if father got tan, his offspring will not be tan Inheritance only by germ cells (gametes), somatic cells (soma) do not function as agents of heredity. Thus genetic information cannot pass from soma to gametes and onto next generation. Charles darwin & alfred russell wallace co-discover the chief mechanism of evolution natural selection (cid:159) The key publication was a co-authored paper done by wallace& darwin, published in.
