In this picture, do you see the same bonobo at different ages? Or do you think this is two different bonobos?
If you guessed "two different bonobos," you guessed correctly!
What makes this tricky is that these two are mother and daughter. Just like human children, bonobo children often resemble their parents.
Semendwa, on the right, is the matriarch of group 1 at Lola ya Bonobo, and Elikya, on the left, is her daughter. The caretakers at Lola ya Bonobo sanctuary say in photos taken at the same age, the two bonobos are hard to tell apart.
