BIO152H5 Lecture Notes - Lecture 2: Design Of Experiments, Monera, Protist
Document Summary
Classifying the diversity of life (a) classify organisms into plants and animals, so separate and easy to group. Protists are being reclassified, so we put them in their own kingdom. Plantlike and animal like protists, fungi like protists. Classifying organisms based on many life of evidence. Comparative anatomy: basic classification, identifying, this is a fish. Behavioral traits: as long as organisms are alive, animals have specific & intricate behavior. Developing evolutionary classifications: must look at closest relative, why do we have a loss of traits, because organisms lived better with this loss. Dna helps us put organisms along the evolutionary tree in the correct way. Biologists test ideas about how the natural world works by evaluating predictions made by hypotheses. Carefully designed experiments are an important tool for hypothesis testing. Other naturalists observed, but he did hypothesis testing. Stages of a scientific process can be divided into several stages: observations, generating a hypothesis, prediction, experimentation/testing, conclusion.
