New reporting from Popular Science explains that squid skin is covered in microscopic hair-like structures resembling the cilia found in the human inner ear. The finding adds to scientists' understanding of how squid sense their surroundings, and readers are sharing the comparison between cephalopod biology and human anatomy as a surprising example of convergent structures in nature.
- 23D DNA structure may explain cephalopods' complex brains●3D structure of DNA may explain how cephalopods evolved complex brains
A new study suggests the three-dimensional organisation of DNA may explain how cephalopods—octopuses, squids and cuttlefish—evolved their unusually complex brains. Researchers point to changes in genome architecture as a driver behind the expansion of neural complexity in these molluscs, a case of sophisticated cognition evolving independently of vertebrates.
- 3Coleoid cephalopod genomes show distinct 3D architecture●Genome reorganisation and expansion shape 3D genome architecture and define a distinct regulatory landscape in coleoid cephalopods
A study published in Nature reports that genome reorganisation and expansion have shaped the three-dimensional genome architecture of coleoid cephalopods, the group including octopuses, squids and cuttlefish. The findings indicate these animals possess a regulatory landscape distinct from other invertebrates, potentially linked to their complex behaviours and elaborate nervous systems, and prompting discussion among evolutionary and genome biologists.
