Scientists have cracked a 140 year-old mystery as to why it’s the father rather than the mother that takes care of the young in some bird species.
Darwin noted in 1871 that in most animals it is the females that spend the most time looking after the young, while males focus on competing with each other for females. Evolutionary biologists argued that this was due to female birds investing significant amounts of energy in producing eggs, making it in their interest to ensure their offspring’s survival by fully caring for them. However, in some species sex roles are reversed, and females produce the eggs but then leave it to their male mates to care for the offspring.
