Directions: In this module, you learned about body size and temperature regulation strategies. Scientists have argued for many years about whether dinosaurs were warm- or cold-blooded, with most recent findings supporting warm-blooded (see this article: http://www.livescience.com/21215-dinosaur-bones-warm-blooded.html). Compare what you know about the Earth’s temperatures now versus then (65 million years ago) and to the animals now versus then. What kind of challenges do you think a warm- or cold-blooded dinosaur might face? Write a two to four page paper regarding this issue.
The paper must be in proper APA format, have a references section, and site at least 2 peer reviewed articles. Please use AAU’s LIRN Library to search for these articles. You may utilize the Academic Resource Center (ARC) for a concise guide on how to use LIRN and for APA formatting guidelines.
