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.

Homo habilis: Our Intelligence Settles.

2.3 Million BCE

92,000 Generations Ago

Earliest Identified Human: Earlier hominins are “humanoid,” due to their human-like features, but the term “human” is reserved for species in the genus Homo. Homo habilis is the earliest known of these “early humans.”

First Earth Explorer: Known as the “handy man,” Homo habilis’s association with the earliest stone tools is evidence of unprecedented level of cognitive ability, including foresight, planning, and the ability to manipulate the environment in complex ways. They used stone tools as well as controlled fire. They were likely the first of “us” to explore most of the Earth. We know they evolved into at least 20 known species of which only Homo Sapiens survive today.

You can think of Homo habilis as a super smart chimp, a 55% smarter one.

Survival: From about 2.4 to 1.4 MYA in Eastern and Southern Africa (in woodlands and grasslands)
Size: 3’4″ to 4’5″ (a bit taller than modern chimpanzees)
Brain Size: around 510 to 600 cm³
Brain to Body EQ: 3.3 to 3.8 (humans=7.4 to 7.8)
