Highlights of what you need to remember LEQ What experiments led to the development of the scientific explanation for the origin of life LEQ How can we use endosymbiosis to support the theory of the origin of eukaryotic cells . Assessment Statements. Outline. . the method for dating rocks and fossils using radioisotopes, with references to . 14. C and . 40. K.. Define half-life. Deduce the approximate age of materials based on a simple decay curve for a radioisotope.. Change over time…. Geology. Began to study rock layers called strata. George Cuvier. Studied fossils. Found extinct species and noticed the deeper the fossil the more unique. Catastrophism. Charles Lyell. Which one?. There are 3 great universal questions. 1) Where did I come from?. 2) Why am I here?. 3) Where am I going?. The answer to the last 2 questions are dependent upon the answer to the first question. . The . formation of a new . species. 15.3 Speciation. What is a species?. A group of organisms with similar characteristics capable of producing fertile . offspring. Members of a . species. . share. the . THEORY OF EVOLUTION. The theory of evolution is scientists explanation of how living things began. .. Also called organic evolution . LIVING ORGANISMS HAVE CHANGED GRADUALLY OVER TIME TO FORM NEW ORGANISMS THAT ARE MORE COMPLEX.. Lauryn. . Langlois. Ashley Mooney. Debora Tolliver. What is Creationism?. Creationism is a theory that states that matter, life, and the world were created by God (or some other supreme being in different religions) out of nothing. . THE ORIGIN AND EVOLUTION OF MICROBIAL LIFE. HOW DID LIFE ORIGINATE?. SPONTANEOUS GENERATION. LIFE ARISING FROM NON-LIVING MATTER. LONG BELIEVED AS THE ACCEPTED EXPLANATION OF ORIGINATION OF LIFE. EXPERIMENTS EVENTUALLY SHOWED IT TO BE IMPOSSIBLE. There is overwhelming evidence for the evolution of life on Earth. . Evolution in summary. Evolution occurs when heritable characteristics of a species change. . Evolution at its most fundamental level simply describes a . Evidence of Evolution. Essential Questions. What is the anatomical evidence of evolution?. How are fossils used as evidence of evolution?. What evolutionary evidence do we have from the field comparative embryology?. 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.. Test on Friday . 4/07. TEST ON TUES. 3/30. Variation in Species Lab. All species have variation. What are some variations you noticed in the size of:. Peas. Grasshopper femurs. Eye width. What are some advantages and disadvantages to these variations?. A mechanism for change in populations.. Any change in the . inherited . traits within a population across generations. Individuals better adapted to their environment tend to survive and . produce more offspring. Mechanisms of concerted evolution. Unequal cross-over. Gene conversion: non-reciprocal transfer of information between homologous sequences; the main mechanism invoked to explain concerted evolution. Entities. . Priya .
