Human DNA is similar to the DNA of a pig, and to a stalk of corn. How did we get to be similar? What does this mean? In this lesson we will see how DNA can be used to trace evolutionary and genetic relationships among organisms and species. The above image is the logo for the Human Genome Project; an international project whose goal is to identify the nucleotide sequence of the human genome. We will learn about this project and how the knowledge gained from it can be applied to the study of evolution and forensics.
This lesson will address the following focusing question:
- How can we use base sequences to trace relationships between organisms within a family and between different species?
This lesson should take approximately 90 minutes to complete.
