Bio 120 - Exam 1 Questions and Answers 100% Solved | Latest Update Synapomorphy - A shared derived character or trait state that distinguishes a clade from the other organisms. Analagous - Having characteristics that are similar because of convergent evolution, not homology. Homologous - Similarity in characteristics resulting from a shared ancestry. Porifera - Sponges No true tissues Mostly marine, aquatic Asymmetric 2 germ layers (endoderm and ectoderm) No coelom Sessile Sessile...

species - evolutionarily independent population or group of populations synapomorphy - a trait that is found in certain groups of organisms and their common ancestor, but is missing in more distant ancestors; identifies monophyletic groups; homologous traits that can be identified at the genetic, developmental, or structural level biological species concept - reproductive isolation between populations (they don't breed and don't produce viable, fertile offspring) - reproductive isolation...

Pacific Hagfish ORDER MYXINIFORMES • Gill pouches may open separately to outside, or by a common opening. • Sensory barbels on nostrils and mouth. • Single nostril opens into mouth, unlike that of lampreys. Water can enter the pharynx through the-nostril as well as the mouth. • Rudimentary eyes (lampreys have well-developed eyes). • One semicircular canal in inner ear (a synapomorphy for the group). • No paired fins, no dorsal or anal fin (although there is a dorsal and anal ...
