The Last Common Ancestor (LCA) of the Great Apes, a.k.a. the Hominidae family, marks a pivotal point in our evolutionary history, encompassing the origins of orangutans, gorillas, chimpanzees, and humans. This ancestor species, likely existing between 15 to 19 million years ago, represents the shared lineage from which all modern great apes have diverged. Current evidence suggests possible candidates for this ancestor ranging from a species within the fossil genus Proconsul from about 19 million years ago to one in the genus Kenyapithecus, dating as late as 15 million years ago. The genus Proconsul survived and evolved from about 22 million years ago to about 18 million years ago in East Africa. Also in East Africa, the genus Kenyapithecus survived and evolved from about 16 million to about 14 million years ago, specifically in Kenya.
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.
