Aliens from outer space-
Sorry, this is not allowed because it is not testable using the Scientific Method. Sheesh!
Something Else-Another possibility that we might think of is predation or cannibalism, which seems to be the best explanation for certain kinds of deformities (frogs with missing limbs).
If this hypothesis is true, then, at minimum:
We should find frogs and/or other pond critters with evidence that their legs have been damaged or bitten off
Chemical Pollution-If this hypothesis is true, then: You should be able to find a likely chemical pollutant in the deformed frog ponds
You should be able to isolate the chemical from the pond water
You should be able to show that the isolated chemical can cause the exact same deformities in the lab
These are minimal predictions; you may have already thought of the fact that chemical pollution should affect all four limbs equally, or that other organisms from the same ponds should show deformities as well
If this hypothesis is true, then: If we mate deformed frogs the offspring should show similar deformities
The deformities should be fairly uniform and predictable The particular deformities should only be found in one species
Ultraviolet Radiation-If this hypothesis is true, then: We should be able to measure unusually high levels of UV radiation at deformed frog sites
We should be able to use these same levels to induce the exact same kinds of deformities in the lab
Can you think of other predictions based on this hypothesis?
Disease (virus, parasite, etc.)- If this hypothesis is true, then: We should be able to find the disease-causing agent (for example, parasites) at the deformed frog ponds
We should be able to find the parasites in the deformed frogs
We should be able to use the same parasite to induce the exact same kinds of deformities in the lab
Loud Rock + Roll Music-Okay, this is testable, but WHY test it??? (get real)
Disease (virus or parasite or...?)
