Aging & Evolution

As most of you probably know, one of my main interests is plants. One of
the ways seed-bearing plants are categorized is according to the length of
their natural life cycles: annuals typically go from cotyledon stage
through reproductive stage and then die within a single year; biennials
reproduce and then die during their second year of life; and perrenials live
for more than one year--these last can be essentially immortal via
vegetative reproduction (naturally occurring cloning). Since there's been
recent discussion of the evolution of aging mechanisms, I've been trying to
find out more about the molecular differences between annual, biennial, and
perennial plants. In the course of doing a Web search I came across a paper
that might be of general interest to list members.

"Twenty-five Problems Not
Solved by Conventional Evolutionary Theory."
