The Mysterious World of Underwater Caves

“We know a lot more about space than we do about the underground waterways coursing through our planet….our world is not one big solid rock… it’s more of s sponge.”

Jill Heinerth shares some of her stunning cave footage and justifies why cave diving is so important here.


Natural Selection and the Evolution of Darwin’s Finches

Another excellent resource from HHMI for teaching evolution and classification: students basically classify 13 of the finch species on the Galapagos and learn about how they came to be how they are along the way.

I’m looking forward to using this in between my evolution and taxonomy units to give students an idea of the thought process scientists go through in classifying a new species, or even a group of new species.

The Genetics of Blue-Eyed People

Scientists at the University of Copenhagen have recently found that people with blue eyes all have a common ancestor–that trait came from a mutation in a single individual. So essentially, all the blue-eyed people are related… How cool is that?!

Introducing… Homo naledi!

A new human species was discovered this year in the Rising Star Cave just outside of Johannesburg, South Africa. Could this be the next step in figuring out how Homo sapiens came to be?

Darwin’s Finches May Soon Be Gone

The organisms that paved the way for evolution are now close to extinction: certain parasites have reached the Galapagos islands and are attacking the finches that Charles Darwin so famously studied. A mathematical model predicted that they could be gone in as soon as 50 years.

…and I thought the North African White Rhino extinction this summer was heartbreaking… 😦
