MORPHOGENIC PHASE. "Did evolution really have an early 'morphogenic' phase during which most major body plans originated?" https://lnkd.in/d-B5nwz View in LinkedIn
AUTONOMOUS DESIGN CHALLENGE. "Biological life is in control of its own means of reproduction, which generally involves complex, autocatalysing chemical reactions. But this autonomy of design and manufacture has not yet been realized artificially." https://lnkd.in/dJJ9HmD View in LinkedIn
CONSERVED BODY PLANS. "Higher taxonomic groups, most notably phyla, poses suites of anatomical features that distinguish them from other groups. Such an underlying anatomical arrangement is called a body plan. Body plans arose rapidly during the radiation of the first animals but have been conserved since their first debut." https://lnkd.in/d2_xbfe View in LinkedIn
ANCIENT BODY PATTERNS. “The basic animal body plans are half a billion years old. Arthropods, chordates, mollusks, echinoderms and others can all be recognized from the first appearance of the animal fossil record. Even so, the striking diversity of living animals shows that dramatic evolutionary transformations have taken place within these ancient patterns." https://lnkd.in/d2_xbfe View in LinkedIn
CONTROL HOMOLOGIES. "One of the most remarkable discoveries of the past few years is that the major elements controlling animal development are quite similar across a wide range of body plans." https://lnkd.in/dx4KvtT View in LinkedIn
STRUCTURAL HOMOLOGIES. "The early formation of distinct germ layers, the establishment of body axes, the differentiation of photoreceptors or the deployment of similar neuronal architectures are examples attesting to deep homologies at the tissue and cellular level." https://lnkd.in/dT-s3Z5 View in LinkedIn
COMMON BODY PLANS. "Animals greatly exemplify how enormous morphological diversity can arise through evolution. However, despite their profound variation in forms, there are clear commonalities in how animal body plans are built." https://lnkd.in/dT-s3Z5 View in LinkedIn
BURST OF CREATIVITY. "The question of how the morphological 'design' of the thirty-five or so animal phyla arose in a burst of creative evolutionary activity in the geologically distant past." https://lnkd.in/d-B5nwz View in LinkedIn
ONLY 36 PHYLA OF ANIMALS. "There are 36 recognized animal phyla, of which but nine (Mollusca, Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Arthropoda, Echinodermata, and Chordata) contain the vast majority of described, extant species. Body plan is one approach to defining phyla." https://lnkd.in/dWhEMWG View in LinkedIn
