Of course not, they only have "free will". But free will is not a requirement for life. Plants, fungi and bacteria live a happy productive existence devoid of having any free will. So does physics also fail to predict how they behave?
No, not really. You can't use Newton's Laws of Motion, or Quantum Mechanics, or Crystallography or General Relativity or the three laws of Thermodynamics or the laws of Chemistry or Geophysical laws... but guess what you can use? Mathematics and Biological laws!
No one knows exactly what DNA is, by the way, but that doesn't mean we can't derive a lot of information from it. No one knows exactly how free will arises from a complex neural network, but again it doesn't mean we can't derive a lot of information from brain cells. Like DNA, we have categorized the different sections in the Brain and can appreciate where certain functions are from.
So I disagree, physics can and does predict group behaviours. Life is just a highly complicated system, but that itself doesn't mean the system can't be studied scientifically and "laws" (or as I often prefer to say "rules") theorized.
