WRITE ABOUT A THEME: EVOLUTION In a short essay(100–150 words), discuss Darwin’s view of how natural selectionresulted in both unity and diversity of life on Earth. Includein your discussion some of his evidence. (For help in writinggood essays, see “Writing Tips and Rubric” in the Study Area ofMasteringBiology under “Additional Resources.”)
Please help with the following prompt using as much details as possible.
"One argument that is often made to invalidate evolution by natural selection is that some features of an organism are so complicated and need to work together in order to precisely function that it is impossible for such structures to arise from simpler ones by the random processes of mutation and selection: complicated design requires a designer. Using evidence from real organisms, explain how a complicated structure can arise from a simpler ancestral feature. You can use either an anatomical feature or molecular one."
Similar anatomical structures shared by related species are called..."

- Explain why anatomical and molecular features often fit a similar nested pattern. In addition, describe a process that can cause this not to be the case.arrow_forwardScientists make use of several parameters in order to determine and analyze evolutionary relationships that exist among living organisms. These parameters are also derived from the concrete pieces of evidence of evolution. To summ arize the valuable ideas in this module, make a conceptual table that can simply and clearly present the importance of these parameters in identifying the underpinning evolutionary relationships among organisms. Complete the following table below. PARAMETERS MECHANISMS BESTEXAMPLEarrow_forward. Structure and function is a central theme to the study of biology. Each major group of organisms has evolved its own body part “tool kit" – a collection of structures that have evolved in ways that make specific functions possible. From capturing food to digesting it, and from reproducing to breathing, organisms use structures that have evolved into different forms as species have adapted to life in different environments. The structure of wings, for example enable birds and insects to fly. The structures of legs enable horses to gallop and kangaroos to hop. a. Think about your own teeth. What kinds of foods do you think human teeth are suited for? b. List at least three ways the structure of human teeth serves the function of eating these food materials. c. Now, finally apply the theme of structure and function to something you're very familiar with - your hands. List out all the ways you can think of that the structure of your hands serve the function of your hands.arrow_forward

How did the Grants catch the finches? 5. What features did they measure? 6. What happened in 1977 to the island? 7. What type of birds were more likely to survive after this event? 8. After the El Nino event in 1983, which birds were more likely to survive? 9. What keeps different species from mating on the Galapagos islands? 10. The most likely scenario explaining the different finches on the islands is that: a) different birds migrated to different islands b) one species evolved into many different species 11.

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.

Even though organisms tend to be of same species, they exhibit different feature or characteristic which is brought about by their adaptation at a certain condition; thus, evolution is dependent on the specific environmental condition the organisms are living in, as well as can be specific to a particular species.
