Why didn't humans evolve to hibernate like many other mammals? Proponents of the adaptation argument argue that individuals adjust and adapt to new situations and conditions, while opponents argue that the population as a whole adapts, which can lead to unforeseen consequences. To account for these and other issues, biologists and palaeontologists use a whole raft of different 'species concepts' that can help separate species from one another and also identify new species.
