Xenoglossy. Xenoglossy (/ˈziːnɵɡlɒsi/ or /ˈzɛnɵɡlɒsi/), also written xenoglossia (/ziːnɵˈɡlɒsiə/ or /zɛnɵˈɡlɒsiə/), is the putative paranormal phenomenon in which a person is able to speak or write a language he or she could not have acquired by natural means.


For example, a person who speaks Swedish fluently, but who is not a native Swedish speaker, has never studied Swedish, never been to a Swedish-speaking country, and never associated with Swedish speakers or had any other source of exposure to the Swedish language, would be said to exhibit xenoglossy. The existence of xenoglossy is not generally accepted by skeptic linguists such as Samarin (1976) and Thomason (1984, 1987, 1996). However, psychiatrist and paranormal researcher Ian Stevenson documented several cases that he considered authentic (Stevenson, 2001).

The words derive from Greek ξένος (xenos), "foreigner"[1] and γλῶσσα (glōssa), "tongue" or "language".[2] Epigenetics. One example of an epigenetic change in eukaryotic biology is the process of cellular differentiation.


During morphogenesis, totipotent stem cells become the various pluripotent cell lines of the embryo, which in turn become fully differentiated cells. In other words, as a single fertilized egg cell – the zygote – continues to divide, the resulting daughter cells change into all the different cell types in an organism, including neurons, muscle cells, epithelium, endothelium of blood vessels, etc., by activating some genes while inhibiting the expression of others.[5]

Épigénétique. Un article de Wikipédia, l'encyclopédie libre.


L'épigénétique est l'ensemble des mécanismes moléculaires concernant le génome ainsi que l'expression des gènes, qui peuvent être influencés par l'environnement et l'histoire individuelle. Ces mécanismes peuvent être potentiellement transmissibles d'une génération à l'autre, sans altération des séquences nucléotidiques (ADN), et avec un caractère réversible.
