One of the starting assumptions of creation science is: The universe is a product of a(n) _ Creator.

Explanation:

Looks like im a little late, but for future reference:

There is a creator who acts alone. > Blackfeet

The earth is flooded. > Apache

The creator creates animals and people. > Both

Birds are important to the creation of the world. > Apache

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
