The First Known Bird Could Fly, But Super Awkwardly

The video discusses the significance of Archaeopteryx in understanding bird evolution, highlighting its unique mix of bird and dinosaur traits. Recent research using synchrotron microtomography reveals its potential for powered flight, though it wasn't a direct ancestor of modern birds. The video also covers advancements in graphene production, introducing a new method for creating large single-crystal sheets, enhancing its strength and conductivity.

What makes Archaeopteryx significant in the study of bird evolution?
