What Did It Feel Like To Be An Early Human?

October 23, 2025

Key Takeaways Copied to clipboard!

  • The documentary series "Human" aims to refresh science documentaries by focusing on evoking emotion and exploring the human experience of our ancestors, rather than just presenting facts. 
  • Paleoanthropologist Ella Al-Shamahi argues that science storytelling often strips away emotion from human evolution, which is a disservice given that humanity is defined by its emotional range. 
  • Homo sapiens were the underdog in a world populated by many human species, succeeding largely due to high numbers, neuroplasticity, and cumulative culture, which allowed for continuous building upon previous knowledge.

Refreshing Science Documentary Style

  • Key Takeaway: Science documentaries should aim to make audiences feel something, not just teach facts, to better engage modern viewers.
  • Summary: The series “Human” seeks to tell the dramatic tale of ancient human family trees by embracing emotional depth. Host Ella Al-Shamahi advocates for putting the human element back into human evolution narratives. This approach counters the tendency to strip emotion when recounting our ancestors’ stories.
Humanizing Ancestor Interactions

  • Key Takeaway: Speculation about the emotional experience of hybrid children between Homo sapiens and Neanderthals is a necessary part of telling the human story.
  • Summary: The existence of Neanderthal DNA in most non-sub-Saharan African populations resulted from interbreeding, which the host calls a “scandal in the family tree.” The series prompts listeners to consider the lived experience of these hybrid children, such as whether they felt ostracized. The existence of remains like Oase One proves these unions resulted in offspring raised to adulthood.
Science Communication and Tribalism

(00:05:16)
  • Key Takeaway: Scientists often overemphasize caveats due to fear of judgment, which hinders emotional connection necessary for communication in the post-truth era.
  • Summary: The tension between science and feeling in documentaries stems from a neurotic focus on caveats and data points. In the current era, people need to feel moved and connected to facts, not just presented with them. Effective communication requires working with ambassadors from within different communities, rather than lecturing them from the outside.
Host’s Personal Journey

  • Key Takeaway: Ella Al-Shamahi’s background as a former Muslim missionary influenced her drive to challenge established narratives in science.
  • Summary: Al-Shamahi studied in the Darwin Building at University College London, initially intending to challenge Darwin’s theories as an arrogant 18-year-old. Her experience leaving a creationist/missionary background informed her understanding of how difficult it is for people to abandon tribal beliefs for new scientific facts. She emphasizes that change often happens when internal community members become ambassadors for new ideas.
Evolutionary Underdog Status

  • Key Takeaway: Homo sapiens were the underdog species 100,000 years ago, frequently failing to establish themselves in territories occupied by other human species.
  • Summary: The cradle of civilization is no longer strictly defined as East Africa; human evolution occurred across the continent for at least 300,000 years. Other species, like Homo floresiensis (the hobbit), existed alongside us, and Homo sapiens were locally extinct in areas like Mount Carmel caves, indicating other species often out-competed us. Neanderthals, our sister species, were better adapted with local immunities, leading to repeated failures for Homo sapiens entering their territories.
Secret to Homo Sapiens Success

  • Key Takeaway: The primary driver of Homo sapiens’ success was cumulative culture, enabled by high population numbers and a brain wired for copying and building upon previous generations’ knowledge.
  • Summary: Interbreeding with other species, like Denisovans (gaining high-altitude adaptation), provided a significant advantage, acting like a ‘cheat code.’ However, the biggest factor was having a large population with neuroplasticity interested in copying each other. This led to cumulative culture, where every generation builds upon the last in art, technology, and science, unlike the ’lone genius’ myth.
Revisiting Neanderthal Perception

(00:16:32)
  • Key Takeaway: The negative portrayal of Neanderthals as ‘knuckle-dragging ape men’ served to elevate Homo sapiens as the pinnacle of evolution.
  • Summary: Neanderthals are our closest relatives, but they have suffered from consistently poor public relations. Evidence suggests Neanderthals engaged in self-beautification, such as seeking bright, iridescent feathers, contradicting the brutish stereotype. The series also highlights that major inventions like agriculture and cities were not exclusive to the Middle East, appearing first in the Americas in the show’s narrative, suggesting inventions are inevitable when cultural conditions are met.
