Understanding the Vampire Squid
This article says the genome of the vampire was finally sequenced, and how that explains the evolution of cephalods. The vampire squid shows us a common ancestor between squids and octopus and has less recombinations than octopuses. In other words, this allows us to see earlier cephalopod evolution. This research, led by the University of Vienna, Austria also stresses how deep sea species have the ability to preserve ancestral traits.
I think that this article is really cool beause them sequencing the vampire squid changed our understanding of the cephalod’s evolution. Being able to see that it has a lot less recombinations that the octopus allows scientists to draw a much more distinct line between squids and octopuses for modern day reasons and evolutionary purposes. Additionally, the fact that we wouldn’t have known any of this information since vampire squids are very hard to study makes this even more fascinating, and it makes me wonder how much more information there is that we don’t know simply because we can’t use “ideal model organisms” or is inaccessible for research purposes.
