Final Jeopardy • They must compete for food and shelter with other living things. This competition causes species to either die out or evolve. *This seems like Natural Selection to me! How does the movement of new individuals into a population help bring about rapid evolution?
$200 Survive and Reproduce Charles Darwin knew that organisms had traits and behaviors that allowed them to do what?
$400 A single species or common ancestor Darwin Argued that all existing species originated from what?
$600 Adapting to their environments Darwin thought that evolution was the result of organisms doing what?
$800 A species with adaptations that are well suited to its environment will survive better and have more offspring. Describe Natural Selection
$1000 Acquired traits are handed down from one generation to the next. Like scars and tatooes. What was Larmarck’s Theory of Evolution
$200 Fossil Records, bacteria evolving to fight medicine, and plants being breed into new plants. Give an example of direct evidence of evolution?
$400 Embryology Homologous structures Vestigial Structures What are 3 indirect types of evidence of evolution?
$600 Appendix Wisdom Teeth Ear wiggling muscles What is an example of a vestigial structure in humans?
$800 Embryos of different organisms are the same at early stages of development. This suggest they have come from a common ancestor How is embryology evidence of evolution?
$1000 They show that changes have occurred within organisms, show that organisms have a common ancestor, shows that enough time has passed for evolution to occur Why are fossils direct evidence of evolution?
$200 Homologous structures show that organisms have a recent common ancestor Why are homologous structures used as evidence of evolution?
$400 They are structures that no longer have a function What is a vestigial structure?
$600 Body parts that have a similar structure but have different functions What are homologous Structures?
$800 Variations are differences in a species that can be good or bad. An adaptation is a variation that is good and helps an oganism survive and reprodice. How are variations different from adaptations?
$1000 It takes time for evolution to occur. Over thousands or millions of years structures get smaller, shut off, then dissapear. Why do some vestigial structures still exist?
$200 Gradual and Punctuated Equilibrium What are two models of evolution?
$400 Punctuated Equilibrium If you found many different fossils for a species in just a few million years what type of evolution would this be?
$600 A species is in a state of equilibrium for an extended period of time followed by a brief and rapid period of change that produces a new species Explain Punctuated Equilibrium
$800 It is a model of evolution that is based on slow and steady changes What is gradualism?
$1000 It is the permanent disappearance of a species What is extinction?
$200 Variations What is the difference in inherited traits of an organism that may lead to a new species?
$400 Species Similar organisms whose members can successfully reproduce.
$600 Relative Dating Method used to estimate the age of a fossil.
$800 Opposable thumbs, binocular vision, and flexible shoulders. List three characteristics of primate.
$1000 Hominids had larger brains. What separates hominids from apes?
$200 Homo habilis Other than Mr. T… who was handy?
$400 Cro-Magnon Who was artsy?
$600 Sudden changes in the DNA of an organism, or an organism finding itself geographically isolated from the rest of its popluation. Name two events that can cause evolution to occur.
$800 Neanderthals Who were the real cavemen? Stone tools and all!
$1000 Not all dead things become fossil. Not all fossils have been found. Give two reasons why the fossil record might be incomplete?
