A. taxon B. cladogram C. binomial nomenclature D. domain A unique trait that is used to construct a cladogram showing evolutionary relationships between organisms is called a ___________________ A. taxa B. molecular clocks C. derived character D. domains Which of the following tells how to write a scientific name? A. The genus name is always capitalized. B. The species name is always capitalized. C. The genus name is NOT capitalized. D. The species name is NOT capitalized. E. Both names are written in italics or underlined. 1 TRUE – FALSE Change the underlined word or phrase to make the statement correct. __________ __________ __________ __________ The least inclusive group to which an organism can belong is the kingdom. Bird wings and insect wings are homologous structures. Most organisms in the kingdoms Animalia and Plantae are multicellular. A species is a larger taxonomic unit than a genus.

Traits that are learned and not inherited are called A __ __ __ __ __ __ T __ __ __ __ __. Which of the following best describes how LAMARCK would explain giraffes with long necks? A. Long-necked giraffes eat more grass than short necked giraffes so their necks grow longer. B. Natural variation in the population produces some longer and some shorter-necked giraffes and longer necked giraffes can reach food more easily. C. Some giraffes have acquired longer necks by stretching to reach food and passed that trait on. D. Giraffes just started out with long necks and haven’t changed. On the Galapagos Islands, Darwin discovered birds with differently shaped beaks. What might this tell you about the eating habits of the birds on different islands? Explain your answer. __________________________________________________________________________________ __________________________________________________________________________________ __________________________________________________________________________________ 3 MULTIPLE CHOICE: Circle the letter of the ONE BEST answer that completes the statement. Structures that have different mature forms, but develop from the same embryonic structure are called _______________ structures. A. Darwinian B. Lamarckian C. homologous D. fossils Because of its similarities to artificial selection, Darwin referred to the “survival of the fittest” as __________________________, A. use it or lose it B. natural selection C. homologous structures D. struggle for existence The natural differences between individuals of a species are referred to as________________________ A. fitness B. natural selection C. adaptations D. variations When farmers select the largest hogs, the fastest horses, or the cows that produce the most milk for breeding it is called ________________.
