Wouldn’t safeguarding mean they still need to attack an aggressor?

If they are vulnerable during pregnancy, why wouldn’t the woman evolve stronger muscles? Then they could also make the men care for infants. I guess suckling would still be a woman thing but that doesn’t take the whole day right.

In your third option, why would the men protect the group and the woman protect the children?

Mine!

Fat is more calorie dense than sugar so the added sugar would lower the calories per gram I think

Beautiful pic with a storyline!

Prime US mentality

Can you know the peak beforehand? And if so, how can I look it up? 😁

Sick find!

I’d guess no, the number of digits and limbs is conserved very well across tetrapods (it’s in their name after all). Fucking with the amount of limbs will probably lead to some developmental errors in the early embryo.

I recently had a course in developmental biology and this is what I can remember the best:

From the moment of fertilization, the egg has a ‘polarity’, thus a direction like up and down, left and right etc. This can be established by e.g. the entry point of the sperm or protein produced by the mother in one side of the egg. From here on out protein gradients and interactions on cell membranes specify where cells are and thus what kind of tissue they should become

This early polarity leads to a certain pattern of cell division. An important part of this is the folding in of tissue layers called gastrulation, creating the beginning for the gastrointestinal tract.

In vertebrates a streak starts to form in the embryo. This is the start of the vertebrae and the neural tube in it. Also blocks of cells called somites start to form. These blocks are very important for all kinds of tissues in the body.

Hox genes make the cells in somites get an identity like head, arm etc. So in the end Hox genes are probably what you are looking for. If leg Hox genes are expressed where fruitfly normally have antennae, you get this horror:

I would, but I also think this would turn bad as soon as this was a big commercially available thing.The people pumping would probably be exploited to the point their kids actually needing the milk would get less.

Ik hou zo erg van dit soort Nederlandse straatjes 😍

Need it for food 7/10

Oh it was fine to begin with, looks extra crisp now for sure.

Damn, interesting! And that chemist sounding name sure does add extra credibility

Just thought about this, isn’t it a bit silly that we all use milli Ah while all the values are above the thousands? Like, 5000 mAh is just 5 Ah

Looks a bit orange mate. Desert dust by any chance?

Nah sorry just kidding around, I think you stumbled upon a classic philosophical problem. You cannot 100% truly know that your senses are correct. I agree with ChatGPT on pragmatism here: you can try proving it all you want, you will never get there. Better to just look at all those pretty flowers nature created in this weird universe!
