Question

Return to the survivorship model you created using dice: You found that the chance of dying from heart disease is approximately one-sixth for each die, indicating that survivorship is essentially the same for each age group. Relate what happened in your model with a realistic projection showing at what ages most humans die of heart disease. Ecologist Aldo Leopold, the father of American conservation, said, "The last word in ignorance is the man who says of an animal or plant: 'What good is it?'... If the biota, in the course of aeons, has built something we like but do not understand, then who but a fool would discard seeming useless parts? To keep every cog and wheel is the first precaution of intelligent tinkering." These are strong words indeed. How do they relate to what you've explored in this exercise?

Explanation / Answer

In population 1, typically constant 1/6 of the population dying at each stage means 17% of population. In population 2 , usually 2/6 means 33% of population die on average at rach stage. You plot this data on airthmetic plot means age verses % of survivors gives you smooth curve whereas logorithem plot give straight line. This plot represent that death rat constant at each stage. The plot represent that most individual die at young age than at older age in airthmatic plot.
