bsc ch.14 core content 1.Which of these is an example of temporal isolation? -One species is nocturnal, and the other species is diurnal (active during the day). 2. Can you complete this concept map that reviews some key ideas about species and speciation? a. Biological b. Morphological c. Allopatric specia d. Sympatric speciation e. Hybrid sonez f. Reproductive isolation g. reinforcement 3. Match each key term to the appropriate description 1.mechanical incompatibility 2.hybrid weakness 3.habitat isolation 4.mechanical incompatibility 5.behavorial isolation 6.gametic incompatibility 7.behavorial isolation 4.Older fossils usually __________. -are found in the deepest strata 5.complete the concept map about macroevolution A.fossil record B. mass extinction C.adaptive radiation D. distribution of species E. gene duplication F. ecological niches G. evolutionary novelties 6.Animals that possess homologous structures probably __________. -shared a common ancestor 7.can you build a phylogenetic tree of vertebrates? a. Hinged jaw b. Four walking legs c. Amnion d. hair, mammary glands e. Fish f. Frog g. Turtle h. Lemur 8.Sequence these levels of biological organization from most inclusive on the left to least inclusive on the right. 1.domain 2. Kingdom 3. Phylum 4. Class 5.order 6.family 7.genus 8.species 9.What does the wide variety of different types of animal eyes represent? -the intermediate forms that probably occurred in the common ancestors of today’s animals 10.Which of the following statements is FALSE? -Organisms can change their DNA in order to become better adapted to their environment. 11.A giraffe and a mouse (both mammals) have the same number of vertebrae in their neck and spine. Which of the following accounts for this? -The vertebrae in their neck and spine are homologous because they share a common ancestor. 12.Sharks (which are fish) and dolphins (which are mammals) are both shaped like a torpedo. Which of the following accounts for this? -Their shape arose through convergent evolution, since that shape is beneficial for animals living in the ocean 13.Which of the following best describes the likely evolutionary steps that led to a complex eye like we see in humans? -a flat sheet of light-sensitive cells; light-sensitive cells in a cup; a pinhole camera without a lens; a pinhole camera with a lens 14.Which of the following best describes what we can determine about the evolution of the eye? -A variety of species exist that are likely to be similar to common ancestors whose eyes evolved to different degrees over time. 15.According to the video, how quickly could evolution take place, going from the simplest light-sensitive cells to a fully-functioning eye?-over the course of 400,000 generations
