In contrast to these materialistic views, Aristotle considered all natural things, not only living things, as being imperfect actualisations of different fixed natural possibilities, known as "forms," "ideas," or (in Latin translations) "species." This was part of his teleological understanding of nature in which all things have an intended role to play in a divine cosmic order.In terms of practical application, an understanding of evolution has been instrumental to developments in numerous scientific and industrial fields, including agriculture, human and veterinary medicine, and the life sciences in general.Discoveries in evolutionary biology have made a significant impact not just in the traditional branches of biology but also in other academic disciplines, including biological anthropology, and evolutionary psychology.Thus, in successive generations members of a population are replaced by progeny of parents better adapted to survive and reproduce in the biophysical environment in which natural selection takes place.This teleonomy is the quality whereby the process of natural selection creates and preserves traits that are seemingly fitted for the functional roles they perform.Moreover, previously held notions about evolution, such as orthogenesis, evolutionism, and other beliefs about innate "progress" within the largest-scale trends in evolution, became obsolete scientific theories.

Natural selection, including sexual selection, is the only known cause of adaptation but not the only known cause of evolution.Other, nonadaptive evolutionary processes include mutation, genetic drift and gene migration.The fossil record includes a progression from early biogenic graphite, In the mid-19th century, Charles Darwin formulated the scientific theory of evolution by natural selection, published in his book On the Origin of Species (1859).Evolution by natural selection is a process demonstrated by the observation that more offspring are produced than can possibly survive, along with three facts about populations: 1) traits vary among individuals with respect to morphology, physiology, and behaviour (phenotypic variation), 2) different traits confer different rates of survival and reproduction (differential fitness), and 3) traits can be passed from generation to generation (heritability of fitness).Repeated formation of new species (speciation), change within species (anagenesis), and loss of species (extinction) throughout the evolutionary history of life on Earth are demonstrated by shared sets of morphological and biochemical traits, including shared DNA sequences.

These shared traits are more similar among species that share a more recent common ancestor, and can be used to reconstruct a biological "tree of life" based on evolutionary relationships (phylogenetics), using both existing species and fossils.

  1. As to those in the health care world, as I said in my first blog post: I have never worked in a place where people are so consistently caring and devoted to alleviating human suffering caused by disease. But many of the forces facing hospitals, doctors, nurses, and others make it really hard to do the job well.

  3. Finally, we will see how the theorem of De Leeuw et al. Dependent type theory solves this issue by introducing in type theory the notion of universe. Voevodsky was a formulation of the extensionality axiom for universe.
