The Big Three: Sapiens, Neanderthals, and Denisovans in a Volatile World

Following our discussion on how severe environmental swings forged the genus Homo, we turn our attention to a fascinating era when the Earth was shared by three highly advanced hominin species.

For hundreds of thousands of years, Homo sapiens were not the only humans navigating a chaotic climate. We shared the Pleistocene landscape with our close cousins, the Neanderthals and the enigmatic Denisovans.

In this session, we will explore how the relentless climate volatility of deep time shaped the destinies of these three distinct lineages. We will examine how each group adapted to drastically different environments and what happens when their paths crossed.

We will dive into an interactive group discussion covering:

• The unique adaptations and survival strategies of each species.
• How alternating climate disruptions across Africa and Eurasia drove their migrations and interactions.
• The genetic legacy and ancient DNA that lives on in modern populations today.
• The ecological and metabolic pressures that ultimately left Sapiens as the sole survivors.
