Other natural historians, such as Buffon, accepted adaptation, and some also accepted evolution, without voicing their opinions as to the mechanism. This illustrates the real merit of Darwin and Alfred Russel Wallace , and secondary figures such as Henry Walter Bates , for putting forward a mechanism whose significance had only been glimpsed ...
More recently, the theory of facilitated variation has been embraced by advocates of an extended evolutionary synthesis, [12] [13] and emphasized for its role in generating non-random phenotypic variation (‘developmental bias’). However, some evolutionary biologists remain skeptical as to whether facilitated variation adds a great deal to ...
Ecosystem classifications are specific kinds of ecological classifications that consider all four elements of the definition of ecosystems: a biotic component, an abiotic complex, the interactions between and within them, and the physical space they occupy. Biotic factors of the ecosystem are living things; such as plants, animals, and bacteria ...
