What makes a Primate, a Primate?

In the past, we’ve concluded that Sasquatch belong to the order of primates for a very good reason; for all the same reasons why humans are in that order.

What makes a primate, a primate, well lets look at what the Smithsonian.com has to say…

    • First, primates have excellent vision. They have forward-facing eyes that sit close together, which allows the eyes’ fields of view to overlap and create stereoscopic, or 3-D, vision. (In contrast, for example, a cow or giraffe has widely spaced eyes and therefore poor depth perception.) Related to this great eyesight is the presence of a post-orbital bar, a ring of bone that surrounds the eyeball. Many primates also have a completely bony socket that encloses the eye. This bone probably protects the eye from contractions of chewing muscles that run down the side of the face, from the jaw to the top of the head. Many mammals that rely less on vision don’t have a post-orbital bar. Because primates depend on their vision so much, they generally have a reduced sense of smell relative to other mammals.
    • Primates are also very dexterous. They can manipulate objects with great skill because they have opposable thumbs and/or big toes, tactile finger pads and nails instead of claws…This is actually a very ancient trait. The earliest mammals had five digits, and over time, many mammalian lineages lost a few fingers and toes while primates kept all of them. Primates also retain collar bones, which allow for greater mobility in the shoulder; mammals that strictly walk on all fours, such as horses, lack collar bones so their limbs are more stable and don’t slip to the side while running.
    • Primates tend to have larger brains than other mammals of a similar size.
    • Primates have smaller litters—often just one baby at a time—and longer periods of gestation and childhood.

Did cooking food make our brains larger?

Now here’s an interesting hypothesis that scientists are putting forward which seems plausible and may explain why the Sasquatch has not evolved in a manner in which we have…

“Eating a raw food diet is a recipe for disaster if you’re trying to boost your species’ brainpower. That’s because humans would have to spend more than 9 hours a day eating to get enough energy from unprocessed raw food alone to support our large brains, according to a new study that calculates the energetic costs of growing a bigger brain or body in primates. But our ancestors managed to get enough energy to grow brains that have three times as many neurons as those in apes such as gorillas, chimpanzees, and orangutans. How did they do it? They got cooking, according to a study published online today in the Proceedings of the National Academy of Sciences.

Humans have more brain neurons than any other primate—about 86 billion, on average, compared with about 33 billion neurons in gorillas and 28 billion in chimpanzees. While these extra neurons endow us with many benefits, they come at a price—our brains consume 20% of our body’s energy when resting, compared with 9% in other primates. So a long-standing riddle has been where did our ancestors get that extra energy to expand their minds as they evolved from animals with brains and bodies the size of chimpanzees?

One answer came in the late 1990s when Harvard University primatologist Richard Wrangham proposed that the brain began to expand rapidly 1.6 million to 1.8 million years ago in our ancestor, Homo erectus, because this early human learned how to roast meat and tuberous root vegetables over a fire. Cooking, Wrangham argued, effectively predigested the food, making it easier and more efficient for our guts to absorb calories more rapidly. Since then, he and his colleagues have shown in lab studies of rodents and pythons that these animals grow up bigger and faster when they eat cooked meat instead of raw meat—and that it takes less energy to digest cooked meat than raw meat.”

What this hypothesis suggests is that by eating cooked food it increases our ability to absorb the nutrients into our neuro-fibers allowing our brains to absorb it’s caloric energies quicker than raw food.

Now this leads to some interesting speculation and negates some of the “Bigfoot are the same as us” people argument. If this theory is correct, folks will have to rethink that philosophy.

In reading the article further, you see an experiment conducted in  other species to bolster the hypothesis.

Since there has been nil reports of Sasquatch using fire, which Homo Erectus first used, it negates their brains developed in a similar manner to ours.

According to an article posted in the Who Lies Sleeping Blog, (An anthropological blog):

“Among primates, animals with larger body sizes grew bigger molars and spent more time eating—great apes of similar size to humans spend about 48 percent of the day consuming calories. The Harvard study says that, while modern humans spend 4.7 percent of their days eating…

Homo erectus and Homo neanderthalensis spent 6.1 percent and 7 percent, respectively, of their active day feeding. Human feeding time and molar size are truly exceptional compared with other primates, and their oddity began around the start of the Pleistocene.

The Pleistocene is the epoch that began about the time that hominines started to make stone tools, and now, it seems, when they started to cook! Cooking may actually have originated with other species that also lived in Africa and came just before Homo erectus, including Homo habilis and Homo rudolfensis. The tools and behaviors necessary to support a cooking culture related to feeding and now necessary for long term survival of modern humans evolved by the time of Homo erectus and before our lineage left Africa.”

To me this has a huge impact on how we should perceive the Sasquatch should this hypothesis be further validated. It would signify that the Sasquatch may be limited in its brain power due to dietary restrictions of eating raw diet, because of the absorption of the nutrients into the brains neuro-fibers.

This would explain things such as a Sasquatch not using complex shelters, (another sign of advanced brain use such as ours) technology development, such as advancement of simple tools or using skins of other animals to protect itself.

Well the jury is still out on this hypothesis, but from some of the studies may very well be on the correct track.

Food for thought for the day… let it cook in your brain for a while.
