'''Darwin's''' theory suggests that [[giraffe]]s developed as they did because an animal with a longer than average neck would have an advantage in reaching foliage that its shorter-necked fellows could not. Therefore it would be healthier, more successful in breeding and hence more likely to pass on its long-necked genes.

While Lamarck's theories were tossed out relatively quickly, Darwin's are proving more stubborn, but are losing traction every day among serious scientists.
