Scientists 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.

1. What is the "mystery of mysteries?
2. The Grants' study on the island of Daphne Major studied what organisms?
3. Where did the 13 species of finches on the islands come from?
4. 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. Examine the graph below. Summarize what happened to the finch population between 1976 and 1978.

Deepening The Concepts Directions: Answer the following questions. 1. How does (a) relative dating and (b) absolute/radioactive datine determine the age of fossils? 2. How does embryology provide evidence for evolution? 3. How do homologous and vestigial structures provide evidence for evolution? 4.

The data may be counts or measurements or lists of species or may take many other forms; however, it is very common that biological data can be represented numerically. Raw data are often too repeti- tive and boring to be appreciated directly. They need to be sta- tistically summarized. The most ordinary way to get started on summarizing data is to enter them in a spreadsheet, such as Excel. Excel also allows one to graph data and do simple analyses. Today and in future labs, you will use Excel in these statistical exercise sections; today we will focus on how to cre- ate and use a spreadsheet. We will start with data gathered by Hollie Putnam, a stu- dent interested in understanding how water temperature af- fected the growth of coral. To determine this, Hollie took cor- als from their native habitat, where the average water tempera- 1 2 3 4 5 Create an Excel file with the data in the lab…arrow_forward
- 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_forwardPlease answer fast. Explanation neededarrow_forwardplease see attachedarrow_forward
