This week's picks

Just when I was starting to get back into the lab, the proofs for my book on Darwinian Agriculture arrived. It's due out in June or July, but I have to check everything and do the index by January. So I only have time to read the abstracts of these interesting-looking papers.

Equitable decision making is associated with neural markers of intrinsic value
"making equitable interpersonal decisions [behaving fairly] engaged neural structures involved in computing subjective value, even when doing so required foregoing material resources... not simply a response to external pressure"
[In other news, people enjoy sex. In both cases, natural selection has shaped our brains based on what maximized contributions to gene pools, in past environments. I wonder how many generations it would take for this to change, in environments where fairness doesn't help you win mates or allies, or where sex is decoupled from reproduction?] "Four participants [of 19] produced no generous/equitable choices; their data could not be modeled and were excluded." [Any difference in the ancestral environments of these four? Or were they finance majors?]

Conflict, sticks and carrots: war increases prosocial punishments and rewards
[On the other hand...] "during wartime, people are more willing to pay costs to punish non-cooperative group members and reward cooperative group members."

Trade-off between warning signal efficacy and mating success in the wood tiger moth
"yellow males had lower mating success than white males" but birds don't eat them.

Global human mandibular variation reflects differences in agricultural and hunter-gatherer subsistence strategies

Fitness consequences of plants growing with siblings: reconciling kin selection, niche partitioning and competitive ability
Impact of epistasis and pleiotropy on evolutionary adaptation


In prior publications, Dr Lieb [the commenter, referring to himself in third person] showed that the enzymes of the arachidonic acid cascade are the agents of natural selection and evolution, differentiating between infertility and reproduction, and between health and longevity, illness and death. Mass deaths in nature have occurred chronically, but seem to have accelerated since December 2010.... As for the stimulant, movement of the magnetic north pole towards Siberia is the most likely, especially as electromagnetic fields paradoxically stimulate and inhibit enzymes directly and indirectly by acting on cell membranes.
