At each point on a 'line', the direction of the 'line' is the direction of the force
on a small test magnet placed in the field at that point.
If two 'lines' crossed at the same point, that means a small test magnet placed
at that point in the field would feel a force in two different directions.
But even if that were true, then the net effect on the small test magnet would be
the vector sum of the two forces, and they would be represented by a single net
force anyway, and therefore by a single field 'line' at that point.
Explanation:
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others
