NATS 1660 Lecture Notes - Temperate Climate, Abiogenesis, Natural Selection
Document Summary
Conclusion influenced by lyell earth is neither static nor young . Galapagos are mostly unique/ unused to people/ relatively fearless. Temperate zone organisms similar to nearby tropical zone than to european temperate zone(2) 1836- did familial things and studied natural science/ 1840 did academic things. Artificial experience: humans have modified other species over many generations by selecting and breeding individuals with desired traits. Organisms related through decent from ancestors that lived in remote past. Tree of life- origin the bottom present at the branch"s. Dissected the logic of darwin"s theory into three inferences based on five observations: organisms overproduce, yet populations generally stay stable, resources are finite (1st inference: struggle for existence, individuals in a population vary, much variability is heritable. 2nd inference: those with favourable traits tend to leave more offspring. Conclusion 22. 2 conclusion: individuals do not evolve, natural selection can amplify or diminish only heritable traits, environmental factors vary spatially and temporally.
