This is an interesting point and not one I spent much time on during my research for the video, thanks for bringing it up ☺. On further inspection it looks like evidence suggests hominins began consuming significant quantities of starch around 600K years ago. But this doesn't explain the linear growth in brain size up till this point, nor the fact that it remained linear afterward. I'll concede that our saliva, which allows the binding of amylose, allows us to consume more starch than our distant ancestors and starch consumption produces A LOT of energy for our brains. But it isn't obvious to me that this mutation made a significant difference in the evolutionary process. It seems like this is a small piece of the "advancements in food processing" factor.
you forgot one more piece of puzzle: Bipedal locomotion. because of our locomotion could hunt gather more stuff and could save more energy for our big brains
While bipedalism allowed our hands to be freer for other uses than just walking, research suggests that opposable thumbs (and tool use) came first. The bipedal trait had both advantages and disadvantages so it's not clear that this was a driving force in evolution. It seems more a byproduct of the desire to use tools and to aid in the nomadic lifestyle.
Yes, teaming is an op tactic. Any species that uses teaming has an advantage over solo players. I would argue that our brains are the most effective weapon in all of animal kingdom. Our tool use and information sharing makes the tools we use our natural weapons. Same as with cooking - eating cooked food is our natural way. Us using a tool we learned/got from another member of our species to get food and then cook it is exactly our species' typical behaviour.
You said the elephant has the largest brain but I could be mistaken but I thought that the blue whale has the largest brain. But I so enjoyed the lecture
9:42 and we are doing this here and now, thank you. I would love to delve into what the 'mass of the soul' theory is, as in that bit of unkown 'magic' we are yet to understand. 😊
2:31 its the ability of the bain and the mass of the creature. Every system can only operate as well as the slowest component, humans are sexy meat machines. 🍖 🙃😊
Great essay. Love the empathy contention. Real smooth work.
Thank you for the great presentation. I am now gonna cook myself a good meal and give my brain power to craft my life in to the future.
Your linier style of explanation along with the graphics is very good and helpful, subbed!
brain size ain't a reason we are so smart, we are smarter than bigger brains and even other kinds.
eating starches and having more copies of amylose gave us the energy surplus to develop big brains.

Increased meat consumption.
Easily one of the best videos on the topic ever prodused.
That scene with the globe must have been a bit strange to record xD

Very useful and enjoyable.
Species name is written in all lowercase
0:19 😂 i liked that, although i felt odd smiling when you didnt 😅
Control of fire. That's it.
But Rob, the earth is only 10,000 years old! 😀🤣😂🙂
6000 😝

Nice video ^^

Depends on the metric. If 'largest' means volume or weight, you would be right. That's not the metric I used for comparison.

Sweat and our ability to eat starch.
And not one 'like and suscribe' so lets throw down one of each for the gent. 😊
It’s okay to be Anglo Saxon
