Warm Up 3-28 In a population of codfish, a scientist notes that some fish have larger fins than others. The differences among the traits of organisms in a population are known as a. variation b. evolution c. extinction d. speciation

Warm Up 3-28 SPECIATION occurs when populations have changed and become 2 different species because…. a. the populations are separated b. the populations look different c. the populations can no longer inter- breed d. the populations adapted

Goldfish Evolution When allele frequencies remain constant, this is called genetic equilibrium, and the population will not evolve.

Goldfish Evolution Select 10 fish and place on your paper towel. The remaining goldfish in the bowl will serve as the “extras” to retrieve new fish as a result of reproduction.

Warm-Up 4/10 Charles Darwin’s theory of natural selection was based partly on his observation that …. DNA is the genetic material of all living things All eukaryotic cells have a nucleus. Some organisms have more offspring than others. Garden pea plants have dominant and recessive traits

Most missed…… According to Darwin’s Theory of Natural Selection…. Populations tend to overproduce Some individuals are better adapted to competition Competition and Predation puts limits on population growth All of the above

Warm-Up 4/12         In the late 1700s most moths in England were light-colored. During the Industrial Revolution pollution from factories darkened tree trunks. By 1886 dark-colored moths were common and light-colored moths were rare. What caused this change in the moth population?            A. Dark-colored moths were attracted to the dark tree trunks.              B. Factory pollution killed the light-colored moths.                C. Dark-colored moths fed on the pollution.             D. Birds ate more light-colored moths because they were easy               to spot. 

A. They all ate different food. B. They all lived in different areas. Write the questions and answer! Warm-Up 4/13 Darwin observed at least 13 different types of finches on the Galapagos Islands.  According to Darwin, what would be the likeliest reason their beaks are different?      A. They all ate different food.      B. They all lived in different areas.      C. Their beak size was different because                            of mutations, but they lived together and ate            similar foods.       D. Both where they lived and what they ate were             different..

According to the theory of natural selection, what is their resistance an example of? a. selective breeding b. asexual reproduction c. overpopulation d. adaptations

Summary What are 4 pieces of evidence that support evolution? F - A -

Summary Why is embryology a good indicator of evolution?  A. All embryos use the same genes at the exact same instant during development.   B. The embryos of various groups of vertebrates all share the same features of early development, suggesting an evolutionary relationship.   C. Embryological development occurs at the same pace in all organisms.   D. The fact that any organisms undergo embryological development at all suggests evolution. 

EQ: How does the fossil record support evolution? 7A Warm-Up 3/30/11 EQ: How does the fossil record support evolution? Based on the branching diagram, which bird does not perch but can fly? What does the fossil record reveal? a. Only dinosaurs formed fossils. b. Species evolved over time. c. Few organisms are extinct.

Draw diagram and write out correct answer! Warm-Up 4/13 Draw diagram and write out correct answer! Species 1 Species 2 Species 3 Species 4 Species 5 D C B A (oldest organism) Scientists often use data from the fossil record to construct cladograms that show the evolutionary relationships among species.
