Every blue-eyed person shares a common ancestor, as blue eyes are caused by a genetic mutation that occured long ago.

April 8, 2021

Ayyyy got denied from the first internship I applied to! To be fair, my primary reason for my attraction to it was its location, not even the projects, and they’re online anyway, so I ain’t all that bothered~

Also I was perusing the syllabus of my chem lab last night (while procrastinating) and found out that you’re only docked 10% if you turn in a lab report up to a day late. Honestly, wish I’d known that back when I turned in that lab report half-finished all those weeks ago (also I could’ve asked for an extension), but hey, you live and you learn. Also,,,, I probably needed something like that to humble me anyway.

Wanna know something that makes me kinda frustrated? No, very frustrated?

The fact that my professor for my organismal biology class never posts videos on time. Like, she’s teaching, what 150 students over the two sections of her course and is consistently a day or two behind on lecture videos. Now! I understand that she fell ill early in the semester, and like, that happens! And she’s super nice and her explanations are generally pretty clear and stuff it’s just that, like, it throws me off my groove dude.

We had our exam 2 today and like,,,,,, ugh. Like the only reason it wasn’t too bad was because I have a half-decent system for searching through my notes for answers (Notability + powerpoints + decent note-taking) and it’s not cheating because everything is ~open note~, but there were four powerpoints that were posted without video lectures, and one of them was posted the first day that people started taking the exam like ????? Y’all. If I was a conspiracy theorist, I’d say that the professor realized that she’d made it in her syllabus that students could take the first two exams and skip out on the next two if they wanted, so she decided to make getting a decent grade on the second exam really difficult so that students have to pay attention for the rest of the semester and at least take the third exam. But I’m not a conspiracy theorist (though I do think I could think myself into circles like one if I wanted), so I think she probably just got behind after she got sick (and for some reason didn’t use spring break to catch up? idk).

All that may be frustrating, but she did post a lecture for today, so I’ll probably get started on that... tomorrow. I’ve watched hours worth of lecture within the past 18 hours for that class (all at 2x speed, mind you, but it actually worked out pretty well because the professor speaks clearly (and slowly) enough that it was effective), so Imma need a bit of a break.

Also,,,, I went to a webinar on getting a job in archaeology today and like,, I know I haven’t done it yet, but I’m not sure if it’s for me. I might’ve just romanticized it, I think. Now, my plan is more related to bioanthropology than material culture, but I did want to try archaeology just to see if it clicks, you know? Maybe it will, maybe it won’t, but the profession itself feels... unnecessarily difficult to break into. Like, sure, to some extent it could be cool to hop around the US, project to project, but I don’t know if that’s a way I’d want to live, especially since the job security as a contractor is literally nonexistent.

KDFJKDJFKDJ SO THE WEBINAR IS WRAPPING UP RIGht and it’s four white ladies and one white guy and one of the ladies was saying like, “you should definitely try to network with people of diverse project interests but also diverse racial backgrounds” and all three of the other women nodded really vigorously and the guy just sat there stonefaced fjgkdjgkdfglkdf I just gotta say, as much as I love white woman activism (and I’m not knocking what she said by the way, it was actually really nice and there was totally no reason for her to say something like that so whether or not it was productive, I say that it’s the thought that counts right here), white men being uncomfortable and unsure in the midst of white woman activism is even better.

[forgot to post this last night whoops!]

My opinion and summary of the podcast How Cooking Made Us Human

I have listened to 2 other podcasts this week. I will make a post about each of them, for more clarity. The first Podcast I have listened to is titled: How Cooking Made Us Human.

(Link: https://www.bridgingthegaps.ie/2019/07/how-cooking-made-us-human-with-professor-richard-wrangham/)

The guest of this podcast is Richard Wrangham; a professor of bioanthropology, who studied primate ecology. His main idea defended in this podcast is: the role of cooking in human evolution. He thought of this from observing the evolution of chimpanzees compared to humans and earlier forms of humans.

He indeed observed the following facts:

- Humans cannot survive efficiently eating only raw wild food.

- Raw food eating still has an interest in modern society: it requires more energy, ergo, it is more suited if you are overweight and want to lose some calories.

- The Homo Erectus evolved a lot, so two main hypotheses are advanced here: a reduction of aggressivity, of the invention of cooking, the main topic of this podcast. Something important to note they are not mutually exclusive.

The main hypothesis defended in this podcast is that cooking caused the evolution of Homo Erectus

This hypothesis is not a consensus in the scientific community for the following reasons:

- There are no traces of cooking and Homo Erectus at the same time.

- Experiments show that eating raw food and eating cooked food leads to the same amount of calorie intake (compared with the excrement’s calorific amount), meaning that raw or cooked food has seemingly no impact on us.

This is not the point of view defended by Richard Wrangham, for he is countering this point of view with these clues:

- Cooking changed behaviour and anatomy

- The more we progress in archeology, the earlier we find traces of cooking, so, even if we have not found traces of cooking dating to Homo Erectus, it is not impossible that, in a few years, it will be proven

- The anatomy of Homo Erectus correlates with this hypothesis, and we virtually have the same size of gut, while predecessors to Homo Erectus had larger guts, most likely due to eating raw food. A smaller gut relates to a more efficient digestive system, with less energy going into digestion, while taking in the same amount.

- At the same time, the brain increased in size, and it was likely thanks to the reduction of the size of the gut, which implied less energy used in the gut, and more available for the brain. This also happened simultaneously with the reduction of the jaw

Personnally, I do not know a lot on the subject, but a point I am wondering is coming from one of the defenses from Professor Wrangham : The fact that we have no evidence does not mean it is impossible. To that, I agree, but this got me wondering: If the hypothesis is actually that cooking lead to Homo Erectus, meaning cooking came before Homo Erectus, how can we disprove this theory? After all, if we find evidence pre-dating Homo Erectus, it does not mean that this is the point that caused this evolution. And assuming we don’t find evidence, we cannot disprove his theory, until we looked up every square inch on planet Earth looking for clues. Therefore, his theory can only be proven right, never wrong. I would say that this is more a point of view, a hypothesis than a theory, to my eyes. However, it might be a thought coming from my lack of knowledge on this topic.

Origins of H. sapiens

-- earliest fossils found in Africa

-- African fossils date to 195,000 years ago

-- earliest H. sapiens outside of Africa were found in China

-- Chinese fossils date to about 100,000 years ago

-- the oldest definitive fossil is about 60,000 years old

-- suggests H. sapiens originated in Africa and then moved to other parts of the world

-- led to the Out of Africa hypothesis
