The observation is for example, lyrebirds have some amazing calls. Falsifiable(hypothesis)-come up with hypothesis that can be made and can be showed to be wrong. Balancing world population and the distribution of resources. The risks from artificial intelligence, nanotechnology, or synthetic biology. Extinciton-from the adjective extinct meaning no longer living or existing, no longer active or burning. Extinct-from the latin verb exstinguere maning to extinguish. Biological species concept-members of same species can mate and produce offspring that are fertile; defines species of term in interbreeding. Members two different species can not produce fertile offspring and may affect genetics(ex: too many chromosomes)
