Today in Astrobiology we discussed and debated the 3 "initial questions" assigned last week. Each class came up with a tentative list of what constitutes life.
In Period 1, the characteristics were: locomotion, has cells, needs water, consume something to get energy, respiration, produces waste, and grows.
In Period 2, characteristics were: either predator or pray, has "natural instincts," has cells with a nucleus, "everything is life," adapts/evolves/grows/dies, eliminates waste, reproduces, has DNA, uses energy, and interracts with the environment.
