The aim was to select a total sample size of 2688 to allow for random selection of sufficient herds stratified on herd type (beef or dairy) and location (province) (Table 2).
Our model demonstrates that kin selection is sufficient and that individual differences in condition and ability are not necessary to promote the emergence and maintenance of leader follower relationships.
Just a few hundred generations of selection are sufficient to allow robots to evolve collision-free movement, homing, sophisticated predator versus prey strategies, coadaptation of brains and bodies, cooperation, and even altruism.
Phenotypic selections in three backcrossing and two selfing generations coupled with SSR based background selection was sufficient for transfer of Xa21, xa13 and xa5 genes into popular deepwater variety Jalmagna background.
Least demanding of the will to believe is "anti-selectionism," which accepts that biological phenomena result from evolution but rejects the Darwinian mechanism of natural selection as sufficient to explain all such phenomena.
Though each has been tested and shown to be accurate, none of the observations and inferences that underlies natural selection is sufficient individually to provide a mechanism for evolutionary change6.
Dawkins shares the view generally held by scientists that natural selection is sufficient to explain the apparent functionality and non-random complexity of the biological world, and can be said to play the role of watchmaker in nature, albeit as an automatic, nonintelligent, blind watchmaker.
In their recent book, The Plausibility of Life [22] Marc Kirschner and John Gerhart have squarely faced the problem that dominates so much of contemporary media attention to biology, and that is the question of whether or not natural selection is sufficient to account for the emergence of the kind of complex biological novelty that current research, not to mention ordinary perception, reveals.
