Nightingale's theory was shown to be applicable during the Crimean War when she, along with other nurses she had trained, took care of injured soldiers by attending to their immediate needs, when communicable diseases and rapid spread of infections were rampant in this early period in the development of disease-capable medicines.
Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution (the idea that species arose through descent with modification from a single common ancestor in a process driven by natural selection) initially met opposition from scientists with different ...
Following the discoveries by Louis Pasteur and others which lead to the Germ Theory, plus other technologies, the role of the environment was dominated by infection control and technological advances. Starting in the 1960s, healing environments have been linked with evidence-based design (EBD), giving the concept a strong scientific base. While ...
This forms an important part of the evidence on which evolutionary theory rests, demonstrates that evolution does occur, and illustrates the processes that created Earth's biodiversity. It supports the modern evolutionary synthesis—the current scientific theory that explains how and why life changes over time.
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.

The mediaeval great chain of being as a staircase, implying the possibility of progress: [1] Ramon Lull's Ladder of Ascent and Descent of the Mind, 1305. Alternatives to Darwinian evolution have been proposed by scholars investigating biology to explain signs of evolution and the relatedness of different groups of living things.
A fact from Nightingale's environmental theory appeared on Wikipedia's Main Page in the Did you know column on 7 December 2007. The text of the entry was as follows: Did you know... that the Environmental Theory by Florence Nightingale (pictured) emphasized how a patient's environment affects his recovery?
The ancestor of each family had arisen through spontaneous generation; environmental effects then caused them to diverge into different species. He speculated that the 200 or so species of mammals then known might have descended from as few as 38 original forms. Buffon's concept of evolution was strictly limited.
