SUMMARY

The discussion centers on the evolution of eye color in hominids, specifically comparing chimpanzees and humans. Chimpanzees exhibit minimal visible sclera, primarily having black and brown eyes, while humans have prominent white sclera that enhance nonverbal communication. Research indicates that eye color in early hominids, such as Homo habilis and Homo erectus, is inferred from DNA when available, but largely remains speculative. The conversation highlights the challenges in reconstructing eye color for ancient hominids due to the lack of definitive evidence.

PREREQUISITES
  • Understanding of human evolution and hominid classification
  • Familiarity with genetic analysis and DNA reconstruction techniques
  • Knowledge of nonverbal communication and its evolutionary significance
  • Awareness of anthropological research methods and literature
NEXT STEPS
  • Research the genetic markers associated with eye color in humans and primates
  • Explore studies on the sclera's role in nonverbal communication
  • Investigate the methodologies used in reconstructing physical traits of ancient hominids
  • Examine the anthropological implications of eye color variations in early human populations
USEFUL FOR

This discussion is beneficial for anthropologists, evolutionary biologists, and anyone interested in the physical characteristics of early hominids and their implications for human evolution.

8) Chimpanzees have much less visible white sclera than

humans. That is, their eyes are basically just black and brown. As

a result, what do scientists think the eyes of hominids looked like?
 
Biology news on Phys.org
Neanderthals lived very recently, so it makes sense that they have eyes that are similar to ours. However, chimpanzees have eyes that are basically all black. Therefore, is there any way to determine the eye color of hominids more primitive than neanderthal like homo habilis, erectus etc?
 
A quick canvass of the lit suggests that early homonim eye color is being figured from DNA.
Where that is not available, it's basically guesswork.

You know you can just google for this stuff right?

Googling "Hominid eye color" led to "Haeckel divided humanity ... based upon... eye color" and "
The genes that control eye color are just a few out of tens of thousands of genes..." These are interesting facts about eye color, but they do not answer my question of what the eyes of our ancestors look like.

Here is what I already know: Humans evolved to have more prominent scleras (white part of eye) because that allows people to track eye movement and thus facilitate nonverbal communication. Our closest living nonhuman relatives, the chimpanzees, have eyes that are basically all black (no sclera, or at least a black one). I was curious if DNA could show whether hominin like homo erectus and homo habilis perhaps had eyes that were in between (that is less visible sclera than modern humans but more so than chimps).
 
I believe it was in one of the articles I had posted, they had brown skin and brown eyes, Peking man actually is thought to have had more European features although the bones were found in Asia, go figure, we've seen some weird things, there are also pictures in those links. I would suggest reading through everything provided and then ask for clarification, that will help to get you better answers. :oldsmile: The palomar series I had linked to in the other thread takes you through an entire series on the subject.

It would also be useful to stick to just one question at a time - the answer in this thread seems to be a moving target: do you want to know what the eye colors are usually thought to be or do you want to know how eye color is assessed when doing reconstructions? Ether way, you have enough to find answers.

You won't find a direct answer to the questions in the references - you need to read between the lines.
Look at the arguments - it's mostly guesswork. You can give them purple eyes if you want. Why is it important?
