PPT-Evolution lesson 4

Species amp Speciation Speciation Gradual process in which one population separates from another AND builds up enough genetic differences to become a new species CONTENT SUMMRY Species amp Speciation. Scientific Theory. Social use of the word “theory”. Not the same as in science. Implies a hunch or a casual guess. Scientific Theory. 1. Highly probable explanation based on vast collections of scientific data. 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 . Bio . HL. Full Classification of Humans. Kingdom - . Animalia.

Ecologists study proximate or “how” questions:. How nutrients flow through ecosystems. Evolutionary biologists study ultimate or “why” questions:. Why does a stickleback fish have armor in one lake but not another?. Chapter 10. Biological Evolution. Evolution the word, has several meanings. Evolution – gradual change to improve or become more complex - change. Evolution – random changes made by chance to get what we see today – goo to you (theory of evolution). 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. . 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. 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. . 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.. 4b.4. The Triple-Note-Tote. Topic. Details. Mnemonic. Triple-Note-Tote. Objectives. Recognize the importance of taking effective notes for remembering information. Organize ideas from an article using the Triple-Note-Tote. 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 . Evolution. – when a species of plants or animals adapts to their environment in order to survive over a long period of time. Key points!. Species. Plants or Animals. Adaptations. In order to survive. Evolution 9/11. Obj. TSW learn form mistakes made on the quiz, and take notes about evolution after the Environmental Science Current Events. P. 34NB. Make a food chain for the following organisms showing the energy arrows and the . . The process by which organism change over time. Based on science, not opinion.. Darwin. :. Evolution is descent with modification. Evolution. :. changes through time. Species accumulate difference.
