TOP REVIEWS FROM EXTINCTIONS: PAST, PRESENT, & FUTURE

by JGJan 1, 2021

I would have preferred less camera focus on the lecturer and more use of illustrations, charts, etc. It was a little boring just watching the lecturer talk.

by EBAug 3, 2020

Excellent overview of pre-human extinctions and their relationship to the current human-initiated 6th extinction.

by GLOct 27, 2020

Dr. Martin made this highly informative class a joy to watch. :0)

An absolutely amazing course with an enthusiastic, engaging professor. I would give more stars if I could! I learned so much and was constantly excited for the next lesson.
