Costs and Consequences of Evolutionary Temperature Adaptation: Response pt. 4

I thought that the author did a good job introducing his subject and setting up his argument and opinion by laying out the main points that he wished to expand on. However, the first issue that caught my eye was that the figures did not match up with the in-text citations. All 3 figures are labeled as “Figure I” but one in text citation refers to “Figure Ia.” Secondly the author points to many different areas of evolutionary temperature adaptation that need to be studied more, but often concludes with a statement about how we do not have a way to look into certain aspects. He does propose some solutions to these issues, but he also points out one glaring problem. Most of the studies that Clarke references have done studies on aquatic organisms rather than terrestrial species. It does not seem that we can necessarily apply the findings of temperature adaptation in aquatic organisms to those terrestrial organisms.
