I'm doing a lab report and if someone could please help me know what buffer is that would be great. It says on my paper that buffer is a nonliving chemical solution, but does that make it biological or non biological?

There is this unresolved question about the sequence of the evolution of the chicken and the egg, but what is really bothering me is about the gender. Did the male evolve before the female or was it the other way round? At what point did the male decide a female has to evolve or at what point did the female decide the male has to evolve?
