- You have now studied three different types of anatomical structures. Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related. 1. Give an example of a homologous structure from this activity: Analogous structures have very different anatomies but similar functions. These are seen in organismsthat are not necessarily closely related but live in similar environments and have similar adaptations. 2. Give an example of an analogous structure from this activity: Vestigial structures are anatomical remnants that were important in the organism's ancestors but are nolonger used in the same way. 3. Give an example of a vestigial structure from this activity:arrow_forwardFossilsa. are the remains and traces of past life.b. can be dated absolutely according to their location in strata.c. are usually remains of soft tissues, such as muscle.d. have been found for all types of animals except humans.arrow_forwardMatch the descriptions/examples types of evidence that support evolution. 1.Biogeography 2.Comparative Embryology 3.Comparative Anatomy 4.Molecular Biology A.Organisms in New Zealand are more similar to organisms in Australia than they are to organisms in North America . B.The embryos of many species have gill pouches even though the gill pouches are not used in these species . C.The forelimbs of the human ,cat ,whale and bat have many similar bones despite the fact that the forelimbs have different functions .

- A. According to Gould and Vrba (1982), when the original cooling function of insect appendages was changed to flying, this is an example of a. inheritance. b. exaptation. c. apatation. d. adaptation. B. When primates first evolved away from their mammalian ancestors, they a. developed a larger and more complex brain. b. increased their reliance on the sense of smell. c. increased the number of canines (for meat-eating). d. all of the abovearrow_forwardEvolution is the theory that species change over time. According to this theory, new species form from existing species through variation and natural selection. The evolutionary process is very slow and the transformation of one species into another requires thousands of years. Several evidences are used to prove evolution and somehow reconstruct how this process occur: 1.Fossil Records. 2.Homologous Body Structures. 3.Vestigial structures. 4.Similarity of embryo. 5.Geographical evidencearrow_forwardDespite the differences in neck length, mice, humans, and giraffes all have seven cervical vertebrae.
