Brain growth may explain why birds lay outsized eggs compared with dinosaurs
✦AI Summary
A new study suggests that the evolution of larger brains in birds necessitated larger offspring, explaining why birds lay disproportionately large eggs compared to their dinosaur ancestors. Researchers found a consistent link between brain size and reproductive investment across vertebrate species.
Why it matters
This research provides a significant evolutionary explanation for a long-standing biological puzzle regarding vertebrate reproductive strategies.
