Mad About Horses

Origins of the Horse


Listen Later

Dr. Chris Mortensen traces the evolutionary path of horses

beginning about 65 million years ago during the age of dinosaurs, leading to
the present day. He discusses how massive environmental and other changes
influenced the physical development and nature of horses over the years.

Dr. Mortensen describes how early horses went from a

forest-dwelling, four-toed creature called Eohippus, to a single-toed,
grassland-residing equid through the process of evolution and adaptability. He
also touches upon various species of early horses, interpreting their survival
or extinction based on how they adapted to the changing world. In addition, the
show explains how the nature of horses made them a classical representation of
evolution.

The first part of this evolution series wraps up with a look

at the proto-horse Marychippus, setting the stage for the emergence of the
Equus genus, to be discussed in the next episode.
