I grew up in an evangelical household and went to a Christian school where they only taught creationism (and a little “micro evolution” but not much).
It’s been many years since I left Christianity but I never really re-schooled myself on all the science I missed out on. I started watching some YouTube videos, and while they’re very informative, I realized they’re about 10 years old. I got to thinking there have probably been a lot of scientific discoveries in the last 10 years. So I googled “recent evolutionary discoveries” and the amount of info that came up was overwhelming.
What’s a good source that I could focus on to learn about discoveries over the last decade or two?
10 years is actually considered not bad by most academic standards. The core ideas of evolution via selection, genetics, and population dynamics (the kinds of things taught in any general biology class in high school and college) really haven’t changed much in 25 years.
You may want to find a biology class and learn about the vocabulary, founding principles, and big ideas. Here is a free open source biology textbook, chapter 18 starts the unit on evolutionary processes. And keep watching YouTube! There are tons of good videos aimed at different levels. “Crash Course” with Hank Green is fantastic and the series covers many academic science topics as an entire course. Biology alone has 20 or 30 ten-minute episodes.
