To research the physics of living systems and its application to understanding evolution and biological systems, you can follow these steps:

1. Start by conducting a literature review: Search scientific databases, such as PubMed and Google Scholar, using keywords like "physics of living systems," "biophysics," "evolutionary biology," and "biological systems." Look for research papers, review articles, and books that discuss the intersection of physics and biology.

2. Read up on the principles of physics relevant to living systems: Familiarize yourself with concepts such as thermodynamics, mechanics, fluid dynamics, and electromagnetism as they apply to biological phenomena.

Using physics concepts, here are two examples that illustrate how physics helps understand concepts in evolution and biological systems:

1. Biomechanics and Evolution: Biomechanics, a subfield of biophysics, studies the application of mechanical principles to biological systems. It helps explain how the structure and mechanics of organisms have evolved to meet specific functional requirements. For instance, studying the wing beat patterns of birds can provide insight into how flight has evolved over time and how different species have adapted to their specific environments. Understanding the physics of wing fluid dynamics and the trade-offs between lift, drag, and maneuverability can shed light on the evolutionary constraints that have shaped these adaptations.

2. Molecular Motors: Physics plays a significant role in understanding the functioning of molecular motors within living organisms, a crucial aspect of biological systems. These motors, such as kinesin and myosin, convert chemical energy into mechanical work, thus enabling cellular processes like muscle contraction and intracellular transport. Physics-based models and experiments have helped uncover the underlying mechanisms, such as the role of Brownian motion, molecular forces, and energy conversion, that drive these molecular motors. By understanding these principles, researchers can gain insights into how motor proteins have evolved and how they function within cellular systems.

Remember, researching and understanding the physics of living systems requires delving into scientific literature, studying relevant principles, and keeping up with ongoing research in the field.
