From Aristotle’s Historia Animalium to Charles Darwin’s iconic tree of evolutionary relationships, hierarchical arrangements of organisms have contributed to an anthropocentric perspective on beinghood.

However, studies within the last decade have revealed that these filter-feeders are more closely related to vertebrates (including humans) than organisms with more complex morphological characteristics.
