Tune in at 6:30 ET today to catch a conversation between two major figures in the field of human evolution and paleontology, Donald Johanson and Richard Leakey. They're having a conversation about the importance of new discoveries in human evolution at New York's American Museum of Natural History.

Johanson discovered the game-changing "Lucy" skeleton fragments and Leakey discovered "Turkana Boy" as well as coining the phrase "sixth extinction" to describe our current era of environmental uncertainty.

According to the AMNH:

The work of these two scientists has produced much of the fossil evidence which forms our understanding of human evolution.

Looking back over careers spanning 40-plus years, these men will share the stories behind their monumental finds and offer a look at what's ahead in human evolutionary research.
