LIFE 102 Lecture Notes - Lecture 16: Carl Linnaeus, Natural Selection, Environmental Factor
Document Summary
Key observations about life: the striking ways in which organisms are suited for life in their environments. The origin of species (1859) - charles darwin. The view that all organisms are related through descent from an ancestor that. Descent with modification (evolution) lived in the remote past. Process in which individuals with favorable inherited traits are more-likely to. Results: favorable characteristics accumulate over the generation (adaption) This process explains the match between organisms and their environment. Environmental factor that restricts survival and reproduction. Natural selection does not create new traits, but edits ro selects for traits. The local environment determines which traits will be selected for or against in already present in the population any specific population. Mutations that promote survival will be carried onto the next generation. New life forms evolve more and more diversity over time. Evolutionary trees made using different types of data (anatomical and dna sequence data)
