Animal Evolution: Stiff or Squishy Notochord Origins?
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.
متن کاملThe Origins of Novel Protein Interactions during Animal Opsin Evolution
BACKGROUND Biologists are gaining an increased understanding of the genetic bases of phenotypic change during evolution. Nevertheless, the origins of phenotypes mediated by novel protein-protein interactions remain largely undocumented. METHODOLOGY/PRINCIPLE FINDINGS Here we analyze the evolution of opsin visual pigment proteins from the genomes of early branching animals, including a new cla...
متن کاملEarly animal evolution and the origins of nervous systems.
Understanding the evolution of early nervous systems is hazardous because we lack good criteria for determining homology between the systems of distant taxa; the timing of the evolutionary events is contested, and thus the relevant ecological and geological settings for them are also unclear. Here I argue that no simple approach will resolve the first issue, but that it remains likely that anim...
متن کاملAnimal Evolution: The Hard Problem of Cartilage Origins
Our skeletons evolved from cartilaginous tissue, but it remains a mystery how cartilage itself first arose in evolution. Characterization of cartilage in cuttlefish and horseshoe crabs reveals surprising commonalities with chordate chondrocytes, suggesting a common evolutionary origin.
متن کاملSquishy Materials
stances they use in the kitchen and the bathroom are not simple liquids or solids. Everyone is familiar with three states of matter: solids, liquids, and gases. However, creams, shampoo, toothpaste, and ketchup all have properties of both liquids and solids. This paper describes demonstrations and laboratory exercises1 that show intriguing properties of squishy substances, defined as materials ...
