1 Evidence of Evolution

2 T h e Fossil Record Fossil: A fossil is the remains or traces of an organism that died long ago. Fossils provide the most powerful evidence of evolution. Fossils are a record of the history of life on Earth. Many fossils have been found of organisms that are no longer living. These extinct fossils resemble organisms that are living today. The fossil evidence shows that past organisms differed from present-day organisms and that many species have become extinct. The fossil record shows when new groups appeared in Earth s history and how they changed over time.

3 By comparing fossils from older rock layers with fossils from younger rock layers, scientists can document that life on Earth has changed over time. Scientists seek to determine both the relative age and the absolute age of a fossil. The relative age is the age of an object in relation to the ages of other objects. For example, when scientists study rock layers, or strata, fossils found at lower strata are deemed older than those fossils found at higher strata.

4 Absolute age is the actual age of the fossil given in years. It is determined through radioactive dating processes. Fossils contain radioactive isotopes that have a half-life. The age of a material can be determined by measuring the amount of a particular radioactive isotope it contains.

5 Law of superposition successive layers of rock are deposited on top of another by wind or water II) Distribution of Fossils A) Stratum the layers in the earth, according to where the fossil is found can help determine its age, and show similarities to other fossils in close layers B) Transitional species fossils that show similarities to those of hypothesized ancestors and later descendent species

6 Biogeography: The Geographic Distribution of Organisms Biogeography is the study of the locations of organisms around the world. It refers to the distribution of plants and animals in the various regions of the world.

7 Homologous Body Structures Species that have common ancestors should have similar characteristics. Similarity in characteristics resulting from common ancestry is known as homology.

8 Homologous structures are body parts that are similar in structure but are different in function. Example: Compare the bone structure seen in the wing of a bat, the flipper of a whale, the foreleg of a cat, and the arm of a human.

9 Analogous structures are Features that serve identical functions and look similar (Ex. Humming bird and Moth wings).

10 Vestigial Structures Vestigial organs are structures that seem to be left over from a previous ancestor and seem to serve no purpose in the living organism. Appendix Vestigial structures are historical remnants of structures that had important functions in ancestors, but are no longer useful to a descendant (Ex. Human tail bone).

11 Remnant of hip and leg bones Example: The skeletons of present day whales reveal remnants of hipbones and leg bones. Example: The human tailbone, or coccyx, is made up of four fused vertebrae that resemble the bones in an animal s tail. Vestigial structures in living organisms: show a relationship to organisms that lived in the past.

12 Many embryos of organisms of different species look very similar in their early stages of development. Embryology Are these organisms the same or different? Are they related to one another? Embryology is the study of embryos and their development.

17 Evolutionary Time Scales Microevolution: Short time scale events (generationto-generation) that change the genotypes and phenotypes of populations 17
