– production of new living organisms or organelles. The law of biogenesis, attributed to Louis Pasteur, is the observation that living things come only from other living things, by reproduction (e.g. a spider lays eggs, which develop into spiders). ***
Fertilisation Fertilisation or fertilization (see spelling differences), also known as generative fertilisation, syngamy and impregnation, is the fusion of gametes to give rise to a new individual organism or offspring and initiate its development. Pro ...
(Conception) – the beginning of an organism's life, initiated by the fusion of gametes resulting in the development of a new individual organism. In animals, the process involves the fusion of an ovum with a sperm, which eventually leads to the development of an embryo. ***

– act or process of bearing or bringing forth offspring. In mammals, the process is initiated by hormones which cause the muscular walls of the uterus to contract, expelling the fetus at a developmental stage when it is ready to feed and breathe.

– term used in the life extension movement and transhumanism to refer to the hypothetical longevity of humans (and other life-forms) under conditions in which aging is effectively and completely prevented and treated. Their lifespans would be "indefinite" (that is, they would not be "immortal") because protection from the effects of aging on health does not guarantee survival. Such individuals would still be susceptible to accidental or intentional death by disease, starvation, getting hit by a truck, murdered, and so on, but not death from aging, some animals can live forever such as the Turritopsis doohmii jellyfish, or the bowhead whale.

(extirpation) – condition of a species (another taxon) that ceases to exist in the chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions. Local extinction can be reversed by reintroduction of the species to the area from other locations; wolf reintroduction is an example of this.
