How Did Jean-baptiste Lamarck Think Giraffes Get Their Long Necks?
Jean Baptist Lamarck proposed that all organisms were not created the way they appear. Rather, they developed and evolved in order to fit in best to their environment. If one organ was needed to be used more to attain maximum survival capacity, ultimately over many generations, that organ would develop in a way that suits the purpose. Similarly, if an organ was no longer needed for optimum survival, it would eventually cease to function. For giraffes, he said that giraffes did not initially have long necks. However, as generations of giraffes stretched their necks to break off leaves on higher trees, the giraffes evolved, so that eventually, their necks became long enough to easily break off the leaves on high trees.
