Yes Bob, it does make sense that the front line is dominated by long leg frogs, just as the olympic broad jump teams are dominated by long leg men, but neither has any relationship whatsoever to the dreams of evolutionists.
Their ability to get there first is simply a mechanical fact that has existred since they were created, but still isn't 'evolution.'
The situation with jump teams is totally different. The fast frogs did not used to exist, as evidenced by the increase in distance covered by the modern frontline variety. Ie the faster variety have appeared and totally dominated a specific range of the overall territory of this frog. That is due to simple natural selection. The frogs will be changing all the time. Some will be slower, some will be faster. The faster frogs happen to be able to spread further into areas not yet inhabited where they don't have any space competition.
