Fill in the blanks below. Write the letter of the correct definition in the blank space on the left. ______ adaptation a. inherited characteristic that increases chances of survival 2______ competition b. organisms with traits well suited to their environment survive and reproduce at a greater rate than less well-adapted organisms in the same environment 3______ natural selection c. a growing population causes a scarcity of resources 4______ gene d. change in a DNA sequence 5_____ mutation e. a segment of DNA that codes for the production of a protein Evolutionary Evidence: Write the letter of the correct definition in the blank space on the left. ______ vestigial structure a. remains of dead organisms ______ homologous structures b. structures in different species which perform the same function, have similar appearance and structure but are not evolved together ______ analogous structures c. structures that are derived from a common ______ fossil record d. in the early stages of development dogs, pigs, and humans resemble one another ______ embryology e. structures that have reduced in size because they no longer serve an important function
