โฆ Synopsis
Biosignature is one of the most important evidences of life available to researchers. However, many complex physical and chemical phenomena can mimic prints of life so closely that special methods are required to make the distinction. In addition to that, life, in principle, can be composed of components which are fundamentally different from those known on Earth. That is why identification of biosignatures should be based upon some phenomenological invariants. Such invariants, within the framework of Newtonian formalism, are introduced and discussed.

Seven invariants, with immediate physical interpretation, are proposed for the strain energy function of nonlinear orthotropic elastic solids. Three of the seven invariants are the principal stretch ratios and the other four are squares of the dot product between the two preferred directions and two
