1. D'Arcy Thompson argued that physical laws and mathematical concepts could explain the diversity of form in the animal kingdom, influencing how animals adapt their locomotion.
2. He introduced the concept of 'transformational morphology,' which examines how changes in form can result from physical forces acting on an organism during development.
3. Thompson's work emphasized that the shapes of animals are not random but are shaped by their environments, behaviors, and evolutionary pressures.
4. He utilized geometric models to describe various modes of locomotion, showing how form is inherently linked to function in movement across different species.
5. His interdisciplinary approach laid the groundwork for integrating biology with mathematics and physics, influencing later studies in biomechanics.
