EvolutionismEvolutionism is a term used (often derogatorily) to denote the theory of evolution. Its exact meaning has changed over time as the study of evolution has progressed. In the 19th century, it was used to describe the belief that organisms deliberately improved themselves through progressive inherited change (orthogenesis). The teleological belief went on to include cultural evolution and social evolution. In the 1970s, the term "Neo-Evolutionism" was used to describe the idea that "human beings sought to preserve a familiar style of life unless change was forced on them by factors that were beyond their control.
Évolution moléculaireL'évolution moléculaire ou évolution du génome correspond à l'ensemble des modifications d ́un génome au cours de générations successives au sein d'une population. C'est le moteur de l'évolution des espèces. L ́étude de l ́évolution moléculaire des génomes tente d'expliquer les changements biologiques au niveau moléculaire et cellulaire. Ceci met en jeu plusieurs disciplines telles que la biologie moléculaire, la génétique, la génomique et la bio-informatique.
Theistic evolutionTheistic evolution (also known as theistic evolutionism or God-guided evolution) is a view that God acts and creates through laws of nature. It posits that the concept of God is compatible with the findings of modern science, including evolution. Theistic evolution is not in itself a scientific theory, but includes a range of views about how science relates to religious beliefs and the extent to which God intervenes. It rejects the strict creationist doctrines of special creation, but can include beliefs such as creation of the human soul.
Male infertilityMale infertility refers to a sexually mature male's inability to impregnate a fertile female. In humans it accounts for 40–50% of infertility. It affects approximately 7% of all men. Male infertility is commonly due to deficiencies in the semen, and semen quality is used as a surrogate measure of male fecundity. More recently, advance sperm analyses that examine intracellular sperm components are being developed.
Non-monogamyNon-monogamy (or nonmonogamy) is an umbrella term for every practice or philosophy of non-dyadic intimate relationship that does not strictly hew to the standards of monogamy, particularly that of having only one person with whom to exchange sex, love, and/or affection. In that sense, "nonmonogamy" may be accurately applied to extramarital sex, group marriage, or polyamory.
DrosophileLes drosophiles (du grec drosos : la rosée et philos : qui aime) forment un genre (Drosophila) d'insectes holométaboles diptères radiorésistants. Elles sont également désignées par le terme plus général de « », ou « mouches à fruits » au Québec. Dans la littérature biologique contemporaine, le nom de genre seul est souvent employé pour désigner l'espèce Drosophila melanogaster, également appelée « mouche du vinaigre », la plus commune dans les laboratoires.
Compétition spermatiqueDans la nature, l’apparente extravagance des traits arborés par les mâles de certaines espèces, et leur sous-jacent impact sur leur survie, inspira Darwin dans le développement de la théorie de la sélection sexuelle. Un siècle plus tard, les biologistes réalisèrent que la polyandrie et le stockage du sperme par les femelles de certaines espèces pouvaient amener à une nouvelle forme de compétition mâle-mâle après accouplement (phase post-copulatoire).
InfidelityInfidelity (synonyms include cheating, straying, adultery, being unfaithful, two-timing, or having an affair) is a violation of a couple's emotional and/or sexual exclusivity that commonly results in feelings of anger, sexual jealousy, and rivalry. What constitutes infidelity depends on expectations within the relationship. In marital relationships, exclusivity is commonly assumed. Infidelity can cause psychological damage, including feelings of rage and betrayal, low sexual and personal confidence, and even post-traumatic stress disorder.
SpermSperm (: sperm or sperms) is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction (forms in which there is a larger, female reproductive cell and a smaller, male one). Animals produce motile sperm with a tail known as a flagellum, which are known as spermatozoa, while some red algae and fungi produce non-motile sperm cells, known as spermatia. Flowering plants contain non-motile sperm inside pollen, while some more basal plants like ferns and some gymnosperms have motile sperm.
Position de l'Église catholique sur la théorie de l'évolutionLa position de l'Église catholique sur la théorie de l'évolution maintient l'inerrance de la Bible, tout en estimant nécessaire de distinguer les différents domaines ou hypothèses, partant, les conclusions certaines des sciences profanes. L’Écriture montre les conséquences dramatiques de cette première désobéissance. Adam et Ève perdent immédiatement la grâce de la sainteté originelle (cf. Rm 3, 23). Ils ont peur de ce Dieu (cf. Gn 3, 9-10) dont ils ont conçu une fausse image, celle d’un Dieu jaloux de ses prérogatives (cf.
