The "Human Odyssey" refers to the movement of humans from our origins in Africa to the present day, in which 7 billion humans have spread to 83 percent of the Earth's surface. This interactive map examines how human migratory paths over the past 200,000 years have been shaped by climate conditions. At the bottom of the map, users can drag the block along the timeline to visualize human migration over that period. Clicking the color-coded circles on the map reveals summary information and images of physical evidence from archaeological sites (yellow dots), geologic evidence of past climates (orange dots), and DNA evidence from human fossils (red dots). The interactive map was designed for laptop or desktop computers and is not mobile-friendly. It is part of the Human Odyssey exhibit at the California Academy of Sciences (previously featured in the 05-12-2017 Scout Report). Below the map, users can click "Learn more" for features, educational resources, and news from the exhibit.

This lovely offering from the MIT OpenCourseWare project takes interested parties through the world of biology via course readings, discussion questions, assignments, and exams. The topics cover genetics, cell biology, molecular biology, developmental biology, and evolution. The Study Terms section is quite useful, as it covers a host of useful terms from cell signaling, immunology, cancer biology, and genetics. Moving on, the recitations are worth a look as they offer lecture notes in a succinct and learned fashion. It's worth noting that visitors can download each set of activities separately or they can also use the Download Course Materials area to download everything at once.
