comment What is the Edward O. Wilson fuss about?
How is the fact that group selection does not hold in theory reconcile with observations / experimental tests? Is there another explanation for inherited religious, social, or political groups?

comment What is the Edward O. Wilson fuss about?
I started reading David Sloan Wilson's work on group selection a decade ago and am surprised that the field still has such a reluctance to move on.

comment From which ancestor species did humans inherit orgasm?
-1 using the term "Invented" makes this question nonsensical.

where have you looked? what do you mean by "I do not need scientific values"? What kind of values do you want? What units? How many different species?

comment Can I estimate leaf temperature from air temperature? What other information would be required?
@nico perhaps because the error of measurement is >= than the error introduced by this assumption (e.g. if the delta-T is ~1-2C the error might be on the order of 10%). If there is a reference, I haven't seen it cited, and this assumption is made ~ 10% of the time - usually in older papers before thermocouples on the leaf surface at the time of measurement were integrated into standard equipment.

comment Features in individuals causing high population variation
The term "striving" and the phrase "the individual should strive" raise concerns like those in the comment by @DQdlM. I would suggest re-phrasing the question.

comment Compare and contrast “Rubisco activity” and “assimilation rate” (is there a difference, and if so, what is it)?
more or less in general. It seems like a less direct measure (since the sugar pool presumably has losses to respiration as well as inputs from assimilation). It also seems more difficult in general, although perhaps less expensive.

how do you calculate k, are the curves in the figure something like e^{-kt}?
