PPT-DAY 1: EVIDENCE of evolution

IMSS BIOLOGY SUMMER 2011 LEARNING TARGETS To understand that biological evolution involves descent with modification To explain and give different types of evidence for the key concept of biological evolution all life shares a common ancestor. 1 miles B-5.5: Exemplify scientific evidence in the fields of anatomy, embryology, biochemistry, and paleontology that underlies the theory of biological evolution.. B-5.6: Summarize ways that scientists use data from a variety of sources to investigate and critically analyze aspects of evolutionary theory.. Unit 6: Seventh Grade. Theory vs. Law. An idea that has . not. been proven to be unequivocally true. Examples:. Big Bang. The extinction of the dinosaurs. An idea or truth that . has . been proven to be unequivocally true. Organism DNA. 1a. Some of the strongest evidence for evolutionary relationships comes from studying the DNA of different organisms.. 1b. The fact that all organisms use the same DNA molecule to code for genetic information suggests that these organisms share a distant ancestor.. LAMARCK (1744 – 1829) .

A change in the traits of one species acts as a selection pressure on the other species. . Chapter 17: Processes of Evolution. Early Beliefs. 19. th. century: discovered species shared many traits, but lived in different parts of the world. Problematic – species only looked similar on the outside, but inside were very different . Pd-2 . Anatomy and Physiology. Evidence for evolution can come in the form of anatomy and physiology. For example vestigial, analogous, and homologous structures. . Vestigial Structure:. The concept of vestigiality applies to genetically determined structures or attributes that have apparently lost most or all of their ancestral function in a given species. An example is the human appendix.. Topics covered here:. Evolution. Classification. Natural Selection is a major mechanism of evolution.
