Fun fact the number of ancestors a male ant has in each generation will follow the Fibonacci series. A male ant has 1 parent (a female) and female ants have 2 parents (a male and a female)

So a male ant will have
1 parent (female)
2 grandparents (1 male 1 female)
3 great grand parents (2 females and 1 male)
5 great great grand parents (3 females and 2 males)

and so on
