And the original question examined by Charles Darwin—what is the mechanism that causes new species to evolve—has yet to be fully explained. And another related question looms: How important are chance events, as opposed to natural selection, to shaping organisms? Another Great Mystery: Why Do...

. The dietary proportions of these two main prey categories were then computed per fish size class (1 cm classes) and habitat for each species separately, and plotted as a function of fish size. A power function (allometric) of the formy=a*xb(whereaandbare constants) was fitted to these...
inecosystemsor biomes determine the types of communities in specific habitats. The food chains and food webs that develop in a community help to drive coevolution among species. As species compete for resources in an environment, they experiencenatural selectionand the pressure to adapt to survive....
Evolution is the process by which a species acquires new traits and through which new organisms are created. This process is slow and gradual and takes many many generations for any discernible changes to occur. Answer and Explanation:1
ESG ratings reveal what tens of thousands of companies are doing to mitigate risks. Even though ratings continue to evolve and expand—some even include cybersecurity and geopolitical risks—they set the standard for companies to see how they rate compared to the competition and how to do better...
