Animal Evolution: Stiff or Squishy Notochord Origins?
نویسندگان
چکیده
The notochord is considered an evolutionary novelty and one of the defining characters of chordates. A new study of an annelid challenges this view and proposes an earlier evolutionary origin in the most recent common ancestor of chordates and annelids.

A main challenge of modern biology is to understand how specific constellations of genes are activated to differentiate cells and give rise to distinct tissues. This study focuses on elucidating how gene expression is initiated in the notochord, an axial structure that provides support and patterning signals to embryos of humans and all other chordates. Although numerous notochord genes have be...

Recent elucidation of the expression and function of developmental genes in different animal groups has made it possible to determine the molecular developmental mechanisms underlying the evolution of various animal body plans. Among numerous evolutionary developmental processes, we have been focusing on the evolution of chordate body plans (Satoh and Jeffery, 1995; Satoh, 1995; Yasuo et al., 1...
متن کاملNew Insights into Vertebrate Origins
p0010 Vertebrates share several distinct morphological characters with three invertebrate groups: lancelets, tunicates, and hemichordates (Figure 6.1). Tunicates, lancelets, and vertebrates have traditionally been considered to be a monophyletic group—the chordates—that shares five morphologic features: a notochord, a dorsal neural tube, an endostyle, a muscular postanal tail, and pharyngeal gi...
متن کاملAn Episode in the Ancestry of Vertebrates: From Mitrate to Crown-Group Craniate
Human beings have a natural interest in their origins. We are vertebrates, within the craniates, within the chordates. Fossils indicate how the chordates separated, in early Palaeozoic times or before, from their latest common ancestor with the echinoderms. The most primitive known fossil chordates retained a calcitic skeleton of echinoderm type (calcichordates) and some of these, the mitrates,...

individual groups making up the animal kingdom, large ensembles named ‘phyla’, are fairly easy to recognize but the evolutionary relationships between the phyla have been very difficult to establish; the phyla were first described in the 19th century, and have been refined since, on the basis of a shared ‘body plan’ within each phylum. That is, all species belonging to a given phylum share a se...
