Question
In a population of bears, which would be considered the fittest?
Options
A.The biggest bear
B.The bear having the largest number of mutations
C.The bear that blends in with its environment the best
D.The bear that leaves the most descendants
Solution
Sol.(d) [Key Concept: Fitness — Reproductive Success (Most Descendants)] Fitness is a measure of an organism's genetic contribution to the next generation. The bear that leaves the most descendants (surviving offspring that reproduce) is the fittest, regardless of size, camouflage, or mutation rate. All other traits are only relevant insofar as they enable the bear to produce more surviving offspring.
