Explore Science-first Philosophy

Eve: Haplogroup L

Author note. 

Explore voice = Exploratory style. Very punchy. Personal, and lively using “me,” “you,” “us,” and “I” freely.

I want you to feel me right there with you. We use “I” and “me” and “us” without apology. If the Explain voice is a bridge, the Explore voice is the hike we take across it. It is lively, reflective, and sometimes a bit raw. It is the sound of a shared exploration where I lead you by the hand, but we both discover the view at the same time.

This is where I get to think out loud. Not with definitions, we aren’t just looking at the facts; we are looking at how they feel and what they mean for our lives. I’m talking to you about what I’ve found and what I’m still figuring out. It is engaging because it is real, and it is reflective because it is honest.

The goal is real advice and enjoyable reading. I want to land on something you can actually use. It’s about being direct, being punchy, and making sure that by the time we reach the end of the page, we’ve both found something worth keeping.

And now the piece.

Eve: Haplogroup L

175,000 BCE
200,000 to 150,000 BCE
7,000 Generations Ago

All humans today share a single grandma, circa 175,000 BCE. We know this because all humans alive today share our ancestor’s haplogroup L genes — from our X chromosome. She was one of many thousands of women living in eastern Africa. Many maternal lines survived for many generations but ultimately over time all the other female lineages died out.

That History Story, 

was first published on TST 5 years ago.

The flashcard inspired by it is this.

All this is part of the broader TST project.
Tidbits are the smallest working units of this project—focused facts, stories, or explanations tied directly to evidence and sources.
This project separates research, synthesis, and reflection so that each can be improved independently without breaking coherence.
