Summary:
Scientists CT scanned fetal whale specimens from the museum's marine mammal collection to trace the development of fetal ear bones in 56 specimens from 10 different whale families. Their findings confirmed that changes in the development of ear bones in the womb paralleled changes observed throughout whale evolution, providing new insight about how whales made the dramatic evolutionary shift from land to sea and adapted to hearing underwater.
