EXPANDED GENE TOOLKIT. "At least part of the potential for developmental evolution during the Cambrian may therefore simply stem from the expansion of the repertoire of regulatory genes in the metazoan ancestor. An increase in regulatory proteins (that can act alone or in combinations) translates into a much bigger increase in possible regulatory network configurations (“topologies”)." https://lnkd.in/dTKCkih View in LinkedIn

PRIOR GENE EXPANSION. "Classes of transcription factors involved in animal development, such as HOX, SOX, POU, F-box, and T-box, emerged most likely before the divergence of the different bilaterian animals but after the split of the basal choanoflagellate lineage from the bilaterian lineage. These metazoan transcription factor classes greatly expanded through duplication in the bilaterian ancestor, just before the Cambrian “explosion”." https://lnkd.in/dTKCkih View in LinkedIn

COLLECTIVE INTELLIGENCE. "Two of the things that make our species special is our collective intelligence and our cumulative culture. Our intelligence is collective because we live in large social networks. From avoiding the misery of boredom and isolation to solving complex problems, we actively seek to learn from others in important ways." https://lnkd.in/dwNsDzt 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

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
