It differentiated between closed awareness, suspicion, mutual deception, and open awareness. The field studies had shown that the type of awareness had a significant impact on interaction — for instance, if patients were not aware of their dying, the nursing was often limited to the absolutely necessary in order to prevent open awareness.
The open awareness context, on the other hand, is a situation where everyone is aware of the condition of the patient. [5] It is distinguished from mutual pretense where everyone knows about the condition but they pretend that they do not or that the patient may recover if he or she is already dying. [5]
Charles Darwin in 1868. Darwinism is a term used to describe a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others. The theory states that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
The current theory of evolution, the modern evolutionary synthesis (or neo-darwinism), explains that evolution of species occurs through a combination of Darwin's mechanism of natural selection and Gregor Mendel's theory of genetics as the basis for biological inheritance and mathematical population genetics.

Evolution provides the field of biology with a solid scientific base. The significance of evolutionary theory is summarised by Theodosius Dobzhansky as "nothing in biology makes sense except in the light of evolution." [78] [79] Nevertheless, the theory of evolution is not static. There is much discussion within the scientific community ...
According to Axe, the research he provides with his book disproves Darwin's theory of evolution, revealing "a gaping hole has been at its center from the beginning." Click through 10 books that ...
Medawar's theory was critiqued and later further developed by George C. Williams in 1957. Williams noted that senescence may be causing many deaths even if animals are not 'dying of old age.' [1] He began his hypothesis with the idea that ageing can cause earlier senescence due to the competitive nature of life. Even a small amount of ageing ...
Known as the Great Dying, the mass extinction that ended the Permian geological period was the worst of the five global catastrophic events in Earth’s history, more devastating, than the one ...
