Researchers from the Geological and Mining Institute of Spain, under the leadership of Dr. Graciela Delvene, have made a remarkable find. They have identified the oldest known evidence of maternal care in shellfish, which dates back 125 million years.
This discovery suggests that certain freshwater species exhibited protective behaviors towards their offspring, indicating a complex level of care in ancient marine life.
The fossil not only provides insights into the evolutionary history of shellfish but also highlights the significance of maternal care in the survival of species over millions of years.
