Remarkably, similar combinations of these traits have evolved independently on different islands, a phenomenon known as convergent evolution. It also shows the techniques used by scientists to study these lizards. c. Synonymous structures. Given that we can't go back in time and see how species evolved, how can we figure out how they are related to one another? We'd also have to choose which characteristics of those organisms to base our tree on (out of their many different physical, behavioral, and biochemical features). are most fit for survival, so most lizards in that habitat would exhibit those most fit b.
