Such shifts of reproductive capability would appear to have adaptive significance to organisms that exhibit it.
We designed a single-center prospective, observational study to test the hypothesis that children with septic shock would have decreased adaptive immune function compared with healthy children and that among children with sepsis, lower adaptive immune function would be associated with the development of persistent infection or new nosocomial infection.
More than that, it is often beneficial for humans to work together with other humans, which means that it would have been adaptive to evaluate the niceness and nastiness of other individuals.
Alternatives have emerged, such as Bitcoin Unlimited, which has no hard coded block size limit; Bitcoin Classic, which would increase the blocksize to 2 megabytes; and BitPay Core, which would have an adaptive block size limit.
Without the mechanism the cooperation would not be evolutionarily stable and without the cooperation the mechanism would have no (adaptive) explanation.
Such urgency would have obvious adaptive and evolutionary advantages: The consequences of a negative event are often dramatic (Ekman, 1992; Öhman, Hamm & Hugdahl, 2000).
YPD CFUs were counted on day 2, and 2-DOGR colonies were counted on day 3, which is prior to the time that colonies would have formed adaptive mutations on the 5-FOA medium (Forche et al. 2003).
In order to maintain the viability of the organism, compensatory mutations in these genes or in any gene encoding directly interacting partners would have been adaptive (Charlesworth and Eyre-Walker 2007).
Thus, although fecundity of selected populations is reduced compared to the controls at late-life stage, under the given protocol of a 21 day generation cycle, flies from the selected populations would have an adaptive advantage in terms of survival and egg output on the day when it matters the most.
"Insect aversions are often filth-related, and that may have adaptive value," Dr. Berenbaum said.
