ontogenesis is a brief and rapid recapitulation of phylogenesis
, determined by the physiological functions of heredity (generation) and adaptation (maintenance).
The link of developmental biology to evolutionary biology has its origin in the comparative embryology of the nineteenth century in the work of von Baer and Haeckel whose "laws"--embryonic divergence and recapitulation--were put forward as being generally applicable to the way in which phylogenesis
Bernard Bichaekjian proposes that evolution of speech and evolution of language have followed two distinct routes through phylogenesis
To rectify this they describe one specific aspect of biological cycles, the mechanism of circadian melatonin secretion of the pineal gland in the chicken to examine the role of circadian processes in virtually all vertebrate species, covering the morphology of the pineal gland, its changes in functions during phylogenesis
, its support of the biological clock, and its regulation of breeding and orientation.
Thus in Goethe's poem, human ontogenesis and the phylogenesis
of humankind are collapsed into a single narrative--that of Prometheus's way from childhood to manhood.
On the basis of this exclusion, ontogenesis is understood as the necessary effect of efficient causes that stem from the determinations contained in the seed; and phylogenesis
is the result of random mutations and natural selection.
The groundedness of the array of social practices conceptualized as the lifeworld, in which the ethical dimension is inextricably linked to the development of ontogenesis and phylogenesis
, (35) affirms its significance as provider of the conditions of a normative framework against which social practice is legitimized.
t]here is an aura of discovery attached to the field of learning disabilities suggesting that the educational world has chanced upon a new kind of child--a new species in scholastic phylogenesis
Correlations of ontogenesis and phylogenesis

She has longstanding expertise in bioinformatics tools and phylogenesis
and focuses her research on virus evolution and molecular epidemiology.
