DIMINISHED CREATIVITY. "Animal evolution was more 'creative' before 500 My ago than since then, when it has been rather conservative, so there is a broad parallel with development." https://lnkd.in/d-B5nwz View in LinkedIn

UNDERLYING GENE NETWORKS. "Conservation of phyletic body plans may have been due to the retention since pre-Cambrian time of gene regulatory network kernels, which underlie development of major body parts." https://lnkd.in/dHpVwii View in LinkedIn

PHYLUM-LEVEL BODY PLANS. "A notable feature of the paleontological record of animal evolution is the establishment by the Early Cambrian of virtually all phylum-level body plans." https://lnkd.in/dHpVwii View in LinkedIn

TWO PHASES OF DIVERSIFICATION. "After the initial “explosion” and formation of most animal body plans (phyla), the subsequent animal diversification only “filled in” the (morphological) space and resulted in more genera and families." https://lnkd.in/dTKCkih View in LinkedIn

CAMBRIAN EXPLOSION THEN STASIS. "Although there are disagreements as to the speed of this diversification, one thing that is clear is that since this time there have been only minor modifications to existing animal body plans." https://lnkd.in/dTKCkih View in LinkedIn

CULTURAL EVOLUTION of the human species has led to the remarkable era of the digital and the internet age. At the same time, biology has leapt forward with synthetic biology and the ability to edit our own genome and potentially affect our own evolution. These tools enable our cultural and our biological evolution, especially as the two start to overlap. Now is the time to look at that overlap. View in LinkedIn

INHERITANCE. "Biological (or genetic) evolution occurs through genetic variation and reproduction, and involves the transfer of genes from one generation to the next. Cultural evolution occurs through the development of customs and languages, and involves the transfer of information either within a generation or across many generations." But genes are information. https://lnkd.in/d-EG9jg View in LinkedIn

FACTIONS. "It is important to distinguish between those who emphasize the differences between biological and cultural evolution, and those who oppose any kind of evolutionary approach to culture. The latter extreme position holds that cultural change does not resemble biological evolution in any respect, that no parallels can (or should) be drawn between biological evolution and cultural change...this position is both theoretically and empirically untenable." https://lnkd.in/dTgbgan View in LinkedIn

MALEABLE. "In biology, for instance, mutation and selection take place at the level of genes and organisms. But while cultural evolution also occurs at the individual level, the unit of selection — behavior — seems more susceptible to drastic change than a gene." https://lnkd.in/dnqbPdK View in LinkedIn
