Revision Evolution MC Answer 6
This is from 2007 Year 10 midyear
Natural Selecion is a mechanism used by Charles Darwin to desceribe Evolution: this has sometimes been referred to as "survival of the fittest". What does the term refer to?
a) the fittest is the best camouflaged
Camouflage means colour or shape that make it hard for a preditor or potential prey (in the case of a tiger) to distinguish the animal from the surroundings.
b) the fittest can survivre anywhere
This means live in all places, air, water, soil tropics, beaches, suburbia.
c) the fittest produces the most offspring
If these offspring then live to reproductive ages, then this would mean that they would dominate. Producing offspring, comes at a cost to the mother. If a cat has 20 kittens a litter, and 17 die, it is not as well off a cat that produce 5 viable kittens.
d) the fittest is the most adaptable to its surrounding
This generally means that the organism has more possiblity and capablity of producing offspring that are themselves able to flourish and reproduce.
