14. TRUE OR FALSE: Vestigial structures may or may not have any function in modern organisms.
11. Vestigial structures are body parts that seemingly have no purpose or function. They once did, but somewhere along the way they lost their functions and are now basically useless. The existence of vestigial structures is on of the strongest evidences of evolution. Which of the following is NOT an example of vestigial structure? * a. Coccyx from the lower portion of the vertebra of human. b. Appendix is a narrow tube that extends from cecum. c. Hair like projections in the nose are called vibrissae. d. Body hair on the chest of man. 12. Rice is a staple food in the Philippines. There are various type of rice in the country, and Filipinos call them by local names such as laon, wagwag, sinandomeng, and angelica. These are some of the different varieties of the rice plant with the scientific name Oryza sativa. yet they all differ. Human intervention can change organism into different or…
1. Embryology does NOT suggest which of the following? A. Developmental mechanisms are unique for every different type of life and share no commonalities. B. Human embryos pass through embryonic stages inherited from their ancestors. C. Developmental mechanisms are evolutionarily modified in a way that is unique to an organism’s way of life. 2. Which comparative anatomy example does NOT support the theory of evolution? A. Bats, humans, and cats have similarly constructed forelimbs and thus suggest a common ancestor. B. The genus of legless lizards are no longer considered lizards and are now part of the snake genus. C. Vestigial organs are structures that are no longer necessary for survival and are thus gradually becoming nonfunctional and reduced in size. D. All statements support the theory of evolution

6. Organisms classified as “birds” share a common feature. What shared derived character defined this taxonomic group? 7. What feature is present in all animals but is not present in birds and reptiles? 8. Reptiles, birds, and mammals are amniotes. I’m addition to an amniotic egg, the common ancestor of all reptiles, birds, and mammals had a thick epidermal layer of scales partially composed of a protein called keratin. Keratinized skin helps prevent water loss in terrestrial environment. A. what type (or form) of Keratinized epidermal structure represents the ancestral character state of all reptiles, birds, and mammals?
