The Origin of Mammal Movement: Harvard Adventures, Part I

Paleontologists today look at more than just fossil evidence to learn about organisms that lived millions of years ago. In this case, we're seeking to answer the question: how, and when, did mammals evolve their specialized movements? Turns out, the next step in this process involves dissecting a giant weasel.  This is part one in a three-part series supported in part by The Field Museum, the Museum of Comparative Zoology at Harvard University, and The National Science Foundation (!!!!). 

Clearing and Staining Fishes

Diaphonization -- otherwise known as clearing and staining -- is one of the most photogenic preparation methods used by research scientists. It's beautiful, but is it practical? We interviewed Dr. Caleb McMahan, Collection Manager of Fishes, on how he uses this technique to answer questions about the evolution of fish! Big thanks to Caleb for taking the time to share his work with us, and to Alan Resetar for lending the reptile and amphibian specimens!... as well as the extra light table because ours broke right before filming. :(
