![]() ![]() We can even see with our own eyes how much our dentition resembles each other – compared to a cow or dog. The appearance of the chimpanzee and human teeth is strikingly similar. Humans have biologically co-evolved with tropical fruits as seed-dispersers and people from temperate climates that “return” to live in the tropics report and enjoy enormous health benefits. See this article here, for more in-depth understanding. Humans were able to survive outside their natural, warm habitat, because of cultural adaptations, like cooking and the use of fire and heating. Humans remain a species that is largely adapted to tropical climates and habitat, including the food sources, as the migration has taken place much faster than most evolutionary changes can take place. However, adaptations that emerged due to selective stressors encountered in the new environment do not signify that humans are now optimally adapted to the new environment. improved milk digestion) and thermoregulation. Thus they had to start eating more hard foods to survive – fallback foods (including savannah type environment)! Was this a potential selective force to drive the evolution of thicker enamel? If yes, strong enamel might be an advantageous adaptation to a diet outside the former fruity paradise.ĭue to the ecological conditions found in temperate climates, cold-indigenous people show to have some traits that have changed and adapted to local diets (i.e. Ripe fruits were less available to humans when they migrated out of the fruit-rich, tropical forests. But again, this is just an observation that lead to an unproven hypothesis!Īdaptation to the migration out of the tropical forests? This would go in line with the instinctual and sensory behavioral difference: while chimps do eat raw meat and insect, to most humans, those animal foods do not look, smell or taste appealing straight from nature (uncooked and unseasoned). Therefore it seems possible that humans are biologically less equipped to hunt and eat meat than Chimpanzees. In humans canines are much reduced in size and have almost lost their function. Human canines do not exhibit sexual dimorphism (Smith et al., 2007). Thus the large canines in males might play a role in this behavior, too. ![]() ![]() However, when they do, the hunting and handling of the prey’s flesh is male business. On average, only 1-2% of their diet is meat, and in some individuals, it’s not clear if they consume meat at all. However, while hunting in chimpanzees is well-studied, there is no evidence to support that the bigger canines serve in hunting or meat-eating. Do the bigger canines in chimps have a function in dietary ecology? Typically enlarged and sharp canines are also associated with meat consumption. ![]()
