As we have reported before, an interesting debate in the scientific community has been the battle of the splitters and lumpers.
The splitters are scientists who consider every fossil specimen they find to be a different species and give it a unique name. The famous anthropologist Louis Leakey was an example of a splitter attaching numerous new names to specimens he discovered. Later it turned out that several specimens which he had given individual names were actually just variations of the same species. In recent years, anthropologists have given individual names to variations of the Neanderthals. Subsequent DNA evidence showed that many of those forms were just racial variations of the same species.
Lumpers suggest that, in general, we see many variations in a species, but we rarely see a new species. In modern days, we have various races that can look very different but are one species. A pygmy and a seven-foot-tall NBA basketball player have vast physical differences, but they are fertile with each other and therefore are one species.
It is becoming increasingly evident that ancient forms were not as diverse as some have assumed. A dinosaur discovered in the 1940s was given the name Nanotyrannus. The picture is an artist’s conception of what they looked like. It is now becoming clear to many scientists that the Nanotyrannus is a juvenile form of Tyrannosaurus rex. Because of their size, the diet of these two specimens was different. With reptiles who continue to grow, they can have a dramatic change in physical makeup as they age.
When we carry the battle of the splitters and lumpers to the question of human origins, the implications become extremely important. Were there many different species of humans that were infertile with each other? Or were they all one species, and the physical variations were simply adaptions to the environment and diet? The Bible indicates that all humans are one and that we all descended from a common human ancestor. The lumpers tend to agree, and the evidence continues to accumulate, verifying that we are all one.
