Your identity is more complex than just being a human
In short: Most people define themselves as humans, but your biological lineage tells a much deeper story. This video explores the diverse phylum Chordata to reveal the specific evolutionary milestones that make you who you are.
The video examines the chordate phylum, identifying the shared characteristics—or synapomorphies—that define this group. It moves beyond simple classification to provide a comprehensive biological pedigree for humans.
Rather than using one term, the speaker proposes a multifaceted sequence of classifications: your being is defined as a cranial chordate, gnathostomal vertebrate, osteichthyen sarcopterygian, tetrapodal amniotic mammal.
