Rather, natural selection occurs as species change to adapt to life: how efficient a tree is at dispersing seeds; a fish's ability to find a safe spawning ground before laying her eggs; the skill with which a bird retrieves seeds from the deep, fragrant cup of a flower; a bacterium's ...
Indeed, selection鈥攁 mathematical certainty in any population in which more individuals are born than reproduced鈥攙ery plausibly acted among extinct hominids much more as a crucial homeostatic mechanism ("stabilizing selection"), than as an agent of change....
Assessment influences every level of the education system and therefore can serveas an important agent for change in science curriculum and instruction. Project 2061 of the American Association for the Advancement of Science has developed an analytical procedure to evaluate the quality of instructional ...
More abstractly, we argue that natural selection operates on systems that compete and vary, and that selfish species typically have an advantage over species that are altruistic to other species. This Darwinian logic could also apply to artificial agents, as agents may eventually be better able ...

We found that the frequency distribution of CORE across all trait pairs differs significantly from that of CORM (Fig. 1B), suggesting the action of selection. For each pair of traits, we transformed the CORM and CORE to Z-scores using Fisher’s r-to-Z transformation and conducted Z-test ...
“Natural Selection” holds that no such change can take place without the influence of altered external circumstances educing or selecting such change… . The hypothesis of “natural selection” totters on the extension of a conjectural condition, explanatory of extinction to the majority of ...
But after my first trip to the festival, I would say it's an event as much about a community of movie lovers as the movies themselves.As Tilda Swinton, star of Ebertfest selection "I Am Love" noted during her Q&A, festivals are about "the collective experience." It's even more true...
are likely to be preserved by natural selection. We demonstrate that natural selection maintains the gene pool of wildA. gifuensispopulations, thereby reducing the impact of large-scale releases. In conclusion, our study reveals the efficacy and safety of usingA. gifuensisas a biocontrol agent....
