In Part One, we established something that the available evidence handles quite comfortably: the female is not the weaker version

Her name was Nkechi. She was thirty-one years old, and she was dying — at least, that is what the doctors privately believed.

It was the spring of 1900. A group of Greek sponge divers, blown off course by a fierce Mediterranean storm, dropped anchor near the small island of Antikythera — a barren, wind-battered speck of land sitting between Crete and the Greek mainland. They were looking for shelter. What they found instead would take another century for the world to begin to understand.

In 1927, a Peruvian archaeologist named Toribio Mejia Xesspe was hiking through the desert plateau south of Lima when he noticed something odd about the ground. Shallow lines. Trenches, really — no deeper than 10 to 30 centimetres — scraped into the reddish-brown surface of the earth to reveal the pale yellow-grey subsoil beneath. They ran in straight lines for hundreds of metres. He noted them, filed a report, and moved on. They were curious. They were not yet miraculous.

Let me be honest with you right from the jump. This piece is personal. It is not a theoretical
think-piece written from the safe distance of academia. I co-founded a clean-tech electric vehicle company from scratch—the kind that starts with a big idea, a small team, an even smaller budget, and an almost embarrassing amount of optimism. So when I talk about the greed for growth and what it costs you, I am not talking from a podium. I am talking from the trenches.

I want to tell you something about confidence that most people get spectacularly wrong.
And I mean that without arrogance — because I got it wrong too, for longer than I care to admit. I walked into rooms with my chest out and my chin up and told myself that was confidence. I practiced certain expressions in the mirror before big presentations. I rehearsed answers to imagined tough questions in the shower until the water ran cold.
I looked confident. I performed confidence quite convincingly, if I do say so myself.

There is a conversation you have been postponing.
You know the one. It has been living rent-free in the back of your head for days, possibly weeks. You have rehearsed it in the shower. You have drafted opening lines in your head while stuck on the Third Mainland Bridge. You have imagined seventeen different versions of how it could go, and approximately sixteen of them ended badly.
So you have said nothing. You have smiled when you did not feel like smiling, agreed when you wanted to disagree, and quietly let something important fester because the alternative — the actual conversation — felt like detonating a device in a room you still have to live in.

There is a category of question that polite intellectual company tends to avoid: the kind that, if you pull the thread long enough, begins to unravel not just a specific mystery but the entire fabric of what we think we know about human history. The Pyramids of Giza are that thread. They have been standing in the Egyptian desert for roughly 4,500 years.
