Because the current trait distribution of a population is often in large part a consequence of its past selective regime, understanding past selection may help predict which species or populations are likely to be especially vulnerable or resistant to particular environmental changes, and prioritize limited conservation resources accordingly.
Enrichment of apoptosis and cell death gene categories among the positively selected genes reveals the past selection pressures experienced by the populations used in this study.
Van Le, Q. et al. Pulvinar neurons reveal neurobiological evidence of past selection for rapid detection of snakes.
"That does not mean that now or in the relatively recent past selection is still favouring larger penises," he said.
Past selection for milk yield or beef production does not seem to have favoured indirectly specific promoter alleles.
'In the past, selection was not transparent, neither was it particularly well defined - do we need someone with a marketing or technical background?
In the past, selection of a managing director, which is made by the 24 representatives of the I.M.F.'s shareholder countries, has taken months.
The most widespread species was less affected by CC, suggesting that past selection on plasticity allows it to survive under variable conditions.
In the past, selection of the constant region (C region) for therapeutic mAbs was based on knowledge retrieved from in vitro analysis of effector functions such as phagocytosis, induction of inflammatory cytokines or chemokines, and antibody-dependent cellular cytoxicity (ADCC).
Those who favor teleological theories of content usually favor an etiological theory of functions, according to which an item's function is determined by its history of selection or by past selection of things of that type.
The app itself is easy to use: you drag the slider to the date you're interested in (today, 1 day ago, 1 week ago, 1 month ago, or you can enter in a custom date via the "in the past" selection).
