Parental care and evolutionary change

Parental care and evolutionary change

wordle

The Nicrophorus genus is over 10 times more speciose than other genera in the Nicrophorinae. Its member species also exhibit far more elaborate forms of parental care than is seen in the sister genera. Could these two observations be causally related? We are using experimental evolution and selection experiments on N. vespilloides to test whether parental care facilitates evolutionary change.
