Cold-blooded versus Warm-Blooded Controversy

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 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.
