5 Questions
What are the five synapomorphies that distinguish chordates from other taxa?
notochord, hollow dorsal nerve cord, endostyle or thyroid, pharyngeal slits, and post-anal tail
What are the three subphyla into which chordates are divided?
Craniata or Vertebrata, Tunicata or Urochordata, and Cephalochordata
What is the significance of the name 'chordate'?
The name 'chordate' comes from the first synapomorphy, the notochord, which plays a significant role in chordate body plan structuring and movements.
What are the two conserved signature indels (CSIs) found in the proteins of chordates?
cyclophilin-like protein and inner mitochondrial membrane protease ATP23
What are the molecular means to reliably distinguish chordates from all other metazoans?
The conserved signature indels (CSIs) in their proteins, specifically the cyclophilin-like protein and inner mitochondrial membrane protease ATP23
Test your knowledge about the distinctive physical characteristics of chordates and learn more about the synapomorphies that set them apart from other taxa.
