HOX COMPONENT GENES. "The number of genes in the Hox cluster varies among animal phyla. Sponges, the most primitive of animals, have at least one Hox gene, whereas arthropods have eight. In mammals, the cluster has been repeatedly duplicated to form four clusters, all slightly different, with a total of 38 genes." https://lnkd.in/dx4KvtT View in LinkedIn

BODY PLAN REGULATORY GENES. "Obviously such sophisticated control systems were not needed in the single-celled ancestors of animals, and thus their evolution is intimately associated with the establishment and initial elaboration of animal body plans." https://lnkd.in/dx4KvtT View in LinkedIn

HOX CLUSTER. "In arthropods, the first genes in the cluster mediate the expression of the head and associated structures, those in the middle of the cluster control genes that produce legs and wings on appropriate body segments, and so on." https://lnkd.in/dx4KvtT View in LinkedIn

HOX GENES. "Many different classes of regulatory genes share a common DNA sequence known as the homeobox, which predates the origin of animals. In complex organisms the Hox cluster specifies the developmental fate of individual regions within the body, and usually the genes are activated and expressed in the body in the same order as their position in the cluster." https://lnkd.in/dx4KvtT View in LinkedIn

MEMES AT WORK. "The current "networked society" is a product of the digital revolution and some major sociological changes. One of these is the rise of the "Me-centered society"." https://lnkd.in/dsHe6fk View in LinkedIn

TINKERING FOR A BILLION YEARS. "Many of the regulatory genes in butterflies, giraffes and squid, for example, are similar, having been inherited from their last common ancestor, the protostome–deuterostome ancestor, which lived at least half a billion years ago. Thus the striking changes in body plans have been accompanied by relatively modest tinkering with the machinery of early development of that long-extinct precursor." https://lnkd.in/dx4KvtT View in LinkedIn

DIGITAL BEDROOM. "The digitalization of childhood can be interpreted as a response to a pre-existing need for new technologies of interaction. The digital bedroom emerged as the outcome of the growing tendency to relocate children’s activities from the outdoor to the indoor." https://lnkd.in/d8-nHvR View in LinkedIn

FROM EXPLOSION TO TINKERING. "Once a large range of morphologies were explored, the major animal forms were fixed and subsequent diversification occurred through finer tinkering and re-use, mainly affecting later development." https://lnkd.in/dTKCkih View in LinkedIn

"VIRTUAL LIFE is becoming more social than the physical life." https://lnkd.in/dsHe6fk View in LinkedIn

POST CAMBRIAN TOOLKIT. "The stability of animal body plans and the underlying GRNs after the Cambrian period have resulted in many of these cis-regulatory elements being maintained ever since as sequences that evolve very slowly and in parallel in different animal groups." (GRNs = gene regulatory networks). https://lnkd.in/dTKCkih View in LinkedIn
