- 1. 1- A) What types of data document patterns and processes of evolution? B) What does homology mean and how is it important with respect to evolution? How types of homology are for providing evidence of evolution? C) does the fossil record provide support for the of evolution? Why do sugar gliders and flying squirrels look so much alike? D) What do we call the similarity between flying squirrels and sugar gliders? E) Provide a complete explanation for the question, what is evolution Vocabulary Solution Answer A) There are mainly four types of data which document patterns and process of evolution; Homology, fossil record, direct observations and biogeography. Answer B) Homology means sharing a similar structure due to relatedness. this is important with respect to evolution because homology tells us that two different animals which shares the homology structures had a common ancestor during evolution. there are two types of homology in evolution; paralogs, which tells us that two copy of one gene located at two different positions on genome inside a single organism has evolved as a duplication event and such genes are called paralogous. while orthologs tells us that if two genes are similar in two different organism's genomes then they were originated in their ancestor. Answer C) Yes, fossil record is one of the data documentation for the evolutionary studies and they help to find the missing links between various points of evolution. sugar gliders and flying squirrels look alike because they share similarity in structures such as white belly, big eyes, same size, and a thin layer of skin under the legs for gliding in the air. Answer D) We call this kind of similarity in same functional structures as analogy.
