Somewhere between 50,000 and 150,000 years ago, our ancestors likely first began communicating ideas through sounds in a more structured way than other species on the planet ever had before.
That’s the beginning of what we now call language, and on an evolutionary scale, it’s remarkably recent (for context, the earliest writing was some 6,000 years ago and we split from the Neanderthals some 700,000 years ago.)
In ‘The First Word,’ a 2008 book by Christine Kenneally, the research into the origins of language are unveiled. I read it earlier this year. Critics liked it when it first came out, and I enjoyed it myself. I read it for two reasons: both as part of my on-going resolution to reading books by women and people of color and to help kickoff a deep dive I’ve been doing into linguistics.
A few weeks ago I decided I just didn’t understand enough of how language developed — or how we’d figure it out. This book was an excellent foundation for me, and I was surprised (and thrilled) by how much evolutionary biology is involved in pinpointing the origins of language. For example, if chimps can do certain language-like things (like gesture, the beginning of language), then humans likely got that from our last common ancestor some four million years ago.
I was so taken by the book and many of the concepts, that I shared some notes below. Consider reading the book yourself, and use this as a jumping off point.
