In cell biology, a biological pathway is a series of interactions among molecules in a cell that leads to a certain product or a change in the cell. Such a pathway can trigger the assembly of new molecules, such as a fat or protein.
In the context of a biological system, bifurcation theory describes how small changes in an input parameter can cause a bifurcation or qualitative change in the behavior of the system. The ability to make dramatic change in system output is often essential to organism function, and bifurcations are therefore ubiquitous in biological networks ...
The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home.. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
The word phyletic derives from the Greek φυλετικός phūletikos, which conveys the meaning of a line of descent. [2] Phyletic gradualism contrasts with the theory of punctuated equilibrium, which proposes that most evolution occurs isolated in rare episodes of rapid evolution, when a single species splits into two distinct species, followed by a long period of stasis or non-change.
In biology, evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms' observable traits.
A 19th-century children's book informs its readers that the Dutch were a "very industrious race", and that Chinese children were "very obedient to their parents".. Mores (/ ˈ m ɔːr eɪ z /, sometimes / ˈ m ɔːr iː z /; [1] from Latin mōrēs [ˈmoːreːs], plural form of singular mōs, meaning "manner, custom, usage, or habit") are social norms that are widely observed within a ...
Although he believed in constant change, he took a very different approach from Diderot: chance and blind combinations of atoms, in de la Bretonne's opinion, were not the cause of transmutation. De la Bretonne argued that all species had developed from more primitive organisms, and that nature aimed to reach perfection.
Teleology in biology is the use of the language of goal ... the zoologist S. H. P. Madrell wrote that "the proper but cumbersome way of describing change by ...
