Fossilized skull reveals origins of a 250-million-year-old shark-like fish!

The video covers four main topics: the Merlin Bird ID app, which helps birdwatchers identify birds using photos; a study on gender stereotypes affecting young girls' aspirations; research on how sea ice loss impacts beluga whale migration; and the discovery of a fossilized skull revealing the origins of chimeras, a group of fish related to sharks. Each section highlights significant scientific advancements and their implications.
