Not only is there evidence of a "drive to giganticism" built into life, there's
even a name for the process: Cope's Rule.

However, the "rule" is highly debated. As good a short explanation of the
alternatives appears in this short letter to Nature:

For a more complete discussion of the discussion, please see:

Cope's rule.  Nature 324: 248-250.

Unfortunately, I couldn't find an on-line copy of the paper. However, I did
find this Brazilian paper (in English) that continues the discussion:
