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)....
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.
Ah, well this just happens to be something I’m into! There is a NOVA movie about the chicxulub (pronounced chick-zaloob) asteroid that hit Mexico and initiated the extinction of the dinosaurs. It’s called The Day the Dinos Died, season 44 episode 21. It’ll show you the ways scientists use different pieces of evidence to create a timeline of the destruction based on new fossils in South Dakota. Very new and cutting edge. They actually found a fragment of the original asteroid.
At the time, our mammal ancestor was kinda like a squirrel rat, nocturnal and lived underground. It would take 5 million more years before our intrepid grandma would venture out of the ground and inherit the Earth. 65 million years later, mammals are the wonderful animals we see today.
Ok, want your mind blown? There is a book called Evolution by Stephen Baxter. It’s fiction but it tells the story of hominid evolution starting from the Chicxulub asteroid. Each chapter is a segment of the life of one likely ancestor on the road to modern humans over those 65 million years. It’s very well written and puts together many well accepted pieces of evidence in a compelling way.
By the way, physical anthropology is the name of the field that covers hominid and human evolution and is it’s own subject.
I mean, I’ve heard that you can typically only survive about three days without water, but what exactly causes your body to fail when you dehydrate too much?...
As water level decreases, the total amount of sodium stays the same. So, essentially it is increasing in concentration. Too much salt interferes with heart cells’ ability to contract together. So less water = more salt = less heart coordination.
Cardiac arrhythmia due to hypernatremia and hypovolumenia can be fatal. There are many changes that occur, but the effect on the heart will kill ya.
