Speciation & Cladistics

Today is the last day of our Evolution Discussion. During our last discussion, we talked about types of evolution/selection and how it leads to new species… Today, we’re discussing how a new species is formed by a process called speciation and how we can illustrate relatedness of species using an instrument called a cladogram.

Watch the video below for more information and examples. Enjoy!


What Did a T-Rex Taste Like???

trexIt may seem like a silly question, but there is a way we can make a pretty significant guess as to what a T-Rex may have tasted like. We can do it using derived characteristics, or homologous structures as you and I call them, and something called a cladogram.

Cladograms are an illustrated way to show relatedness of species both current or extinct. Today we’ll be introduced to cladistics using an online module. The good news is by the end, you will be able to predict with great certainty what a T-Rex most likely tasted like.
