Why did T-Rex have short arms?
to report Acta Paleontology JournalThe reason why a bone-crushing dinosaur like the T-Rex had short arms was that these animals mistakenly bit each other’s arms while eating.
For now, this is just a hypothesis. Quoted from John Hutchinson: “It is a good story. “But in the end, I think we really don’t know what’s going on.”
He, who studies the biological movement mechanism of terrestrial organisms (both extinct and living species), continues: “It seems that the hands have not become shorter, but the legs have become longer and the body has become bigger.”
Mr. Hutchinson says about the evolutionary process: “As the T-rex evolved, which led to larger heads and bipeds, the use of arms and hands became less and less. They used their heads to catch and kill their prey, so they had little use for their arms. An animal can devote only a percentage of its body mass to a specialized subject. It cannot be a versatile animal. “So you either have a creature that is moderately evolved for everything, or you have a creature like the T-Rex that is designed purely to hunt and kill.”
