This week on Animal Instinct, host Celia Kutcher is going nuts for squirrels! Welcoming the one of the country's experts on the small mammal, Dr. John L. Koprowski, to the show, he explains the evolutionary background of the squirrel and that the squirrel can be found on every continent, minus Antarctica. Dr. Koprowski also explains the various colors of squirrels throughout the country, such as a black or orange squirrel, and the ill-attempts of taming a wild squirrel. After the break, Dr. Koprowski shares the details behind the lifespan, mating habits, and social behaviors of the different types of squirrels. Tune in to learn all about these interesting creatures and what to do if you find a lost baby squirrel. This program was brought to you by Edwards VA Ham.

"Squirrels were one of those species that at an early age something I could look out the window [and see]... whenever I would think about biology and what I might want to do in the future with my life, I would always come back to find squirrels in that somehow." [2:36]

"They've actually been around for a really long time. They first start to show up in the fossil record about 35 to 40 million years ago." [4:19]
