Artificial selection is the breeding of organisms to produce specific traits. An example would be to breed two specific dogs to get one dog with different traits such as herding, agility, and playfulness.
We explain this puzzle-piece-like build as proof of tectonic plate shifting. As magma inside the earth moves, so do the continental plates on top of the magma. The continents used to be fused together in one larger continent called Pangea. Over the course of 1000s of years, the plates have shifted.
tldr: tectonic plate movements cause this phenomena

The maximum probable speed of walking is restricted mainly by two factors, that is, the length of the leg and the free fall acceleration. The animals with longer legs exhibit higher maximum walking speed, while the animals with very short legs exhibit low maximum walking speed.
The large birds like pheasants usually walk brief distances, however, birds like chickadees never walk. In the case of pheasants, they exhibit a higher maximum walking speed, on the other hand, the chickadees exhibits a low maximum walking speed. Thus, the chickadees should never walk, they should fly or hop.
Also, more energy is utilized in flying than in walking. Therefore, large birds like pheasants usually walk brief distances so that energy can be saved.
