Having abs is 100% to do with body fat percentage, you need to lose weight if you want abs to show through (everyone has abs) whether these abs are large and impressive however depends from person to person and you can increase them with ab exercises. But as I said to get these abs to show you need a low 8-12% bodyfat percentage.
There is no number for everyone- each person has a different number.
YES! one direction has abs
The first person who got abs was the first person on earth. Everyone has abdominal muscles, but not every person has developed abdominal muscles.
