And they asked us this question. They say, "Why model just in the sagittal plane or the vertical plane, when you're telling us these animals are moving in the horizontal plane?" This is a good question.
og de stillede de os dette spørgsmål. De sagde, "Hvorfor skal vi kun modellere det sagittale, eller lodrette, plan, når I nu siger, at disse dyr bevæger sig i det vandrette plan?" Det er et godt spørgsmål.
