Understanding Evolution Through a Dry Lab
When we talk about evolution, we’re referring to the process by which populations of
organisms change over generations through mechanisms like natural selection, mutation,
and genetic drift. But how do educators make this abstract process tangible for students?
Enter the dry lab—a type of laboratory activity that doesn’t require wet chemicals or
physical specimens but instead uses simulations, data analysis, and interactive models.
In the context of evolution, dry labs often involve examining fossil records, comparing
anatomical structures, or analyzing DNA sequences—all virtually or through guided
worksheets. The evidence of evolution dry lab answer key is a vital tool that helps
