Randy Fairchild. “The Case Against Animal Testing”. Helium – “Nor is it sufficient to draw the species barrier. What difference does it make, ethically, that humans cannot reproduce with other animals (and therefore are not the same species)? What defines a species drifts over time in a process called evolution, and all animals diverged from one another at one point in the past, just as humans may diverge from one another and form new species in the future.”
