We once thought that we were always as we are now, but now know that animals had to evolve for millions of years to become human. Likewise, the universe we see wasn’t always as it is now. We might think that matter always was but even now, stars are producing complex atoms from simpler ones by the process of nucleosynthesis. The elements of the periodic table (Figure 4.21) had to evolve, and so did we, so the evolution of life is just continuing the evolution of matter.
