For this lab we will use NFL Scouting Combine data for drafted
running backs and wide receivers from years 2012-2014.The combine
is a series of tests to evaluate college football players ahead of
the NFL Draft. The dataset is available on Canvas. To perform the
hypothesis tests below, you will need to upload the data to StatKey
and select the appropriate columns. For guidance, refer to the
StatKey guide.The dataset contains the following variables:

Snakes have lost their limbs over the course of
evolution. Recent data show a reduction in Shhexpression
in their limb fields due to loss of a portion of the limb enhancer,
noting that other enhancers remain intact.
First, indicate whether this is an example of heterotopy,
heterochrony, heterometry, or heterotypy, defining your chosen
term. Second, describe how you might use the mouse embryo as a
model system to test the hypothesis that this reduction in
Shh expression in the limb...
