What is geoscience?
Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...

One slight correction: evidence indicates that the americas were colonized before the ice age corridor opened. It is now thought that the americas were colonized via short excursions near shore via boats resulting in the coastal areas being inhabitated in only ~500 years from alaska all the way down to the tip of south america. This is thought to be the same way that australia was inhabited 60,000 years ago. The oldest settlement sites are now underwater.
Isn't that more of a recent discovery though? I only mention it cos this comic is from 2016, which, as much as I don't want to acknowledge the passing of time, is 7yrs ago.
It was understood by the early 2010s that the timeline was off. Scientific American ran an article about it at the end of 2012 but it does not surprise me that Monroe would still go by the old timeline in 2016. I only knew about it years ago because I was an undergrad and one of my professors worked extensively in Alaska and neighboring areas during his PhD.
