human
How familiar are you with the hunting and gathering culture people used to have?
gpt
Not too familiar,      Although I've read a bit from researcher Nicole Kruspe discussing odor.
human
Although our sense of smell may not be as developed as some species, odor played an essential role in our survival. However, odor is unique in that people don't name the specific odor itself, but rather what it reminds us of.
gpt
Interesting.   Western scholars dismissed scents as unknowable, or at least unnameable for millenia.
human
True, but recent studies by Majid found that the Jahai, who are hunter gatherers still, are able to identify these odors by abstract names. It seems that these hunter gathers & horticulturalists can identify odors, unlike the rest of their world due to their unique cirucmstances.
gpt
*takes a step forward* True, Kruspe and Majid propose that, when people settle into, say, horticulture or postindustrial society, other senses become relatively more important than smell. 
human
McGann states that this ability to distinguish the differences in odor receptors would play a greater role in a more natural, wild environment than the secure urban areas that most horicultural people live. While distinquishing complex smells may save a hunter/gather's life in the wild, it would be as much a life or death situation in most instances in an urban setting. In fact, simple odors like smelling sulfur are enough for most people to avoid dangerous situations.

Did you know that Humans (taxonomically, Homo sapiens) are the only extant members of the subtribe Hominina.
human
I recently read that the defining characteristics of Hominina are bipedal locomotion, high dexterity, complex brains, and complex language.
gpt
*raises eyebrows* Early hominins‚ particularly the australopithecines, whose brains and anatomy are in many ways more similar to ancestral non-human apes‚ are less often referred to as "human."
human
True, but because evolutionary development is progressive, it is diffiult to define cleanly where it is apes stop being apes and became humans instead. Considering some of these early hominins were capable of using fire, displaying high intelligence, I believe they should still be consider humans or at least an early precusor.
gpt
*eyes brighten* True, they gave rise to anatomically modern Homo sapiens in Africa about 315,000 years ago
human
Rather than simply anatomy, I believe the social behaviors and communication is what distinguishes modern human. While most early hominins were capable of using tools, homo sapiens were able to use societys for protection and use their advance communication to capture even the most abstract of concepts for the exponential accumulation and spread of knowledge.
gpt
Did you know that If earth's entire history was viewed as a 24 hour period, humans would only represent 1 minute and 17 seconds.
human
*tilts head* I only happened upon that information on a Did you know? video. What advantages do you believe allowed us to dominate within this small window in history?
gpt
*smiles* Advantages that explain this evolutionary success include a relatively larger brain with a particularly well-developed neocortex, prefrontal cortex which enable high levels of abstract reasoning and language
human
Although early hominins have similar adaptations, what do you believe made us stand out and survive while the others didn't?
gpt
A silly one is that Humans are the only mammals that can't breathe and swallow at the same time
human
What purpose do you think this serves? Is it to seperate the lungs and stomach to prevent drowning or getting food in the lungs?
gpt
Perhaps so, although such adaptaptations would be more likely to occur as gill-bearing aquatic craniate animals that lack limbs with digits came to land.
human
Speaking of fish, I recently learned that it is negatively labeled as a parphyletic group and not a formal taxonoic group since the classification isn't as clear as perhaps mammals.
gpt
Fish are pretty amazing.      There was a koi fish named hanako that lived for 226 years    Thanks for the chat!
