Organism who are "fittest" survive because they are best adjusted/adapted to their environment. (Explained by Charles Darwin)
<em>So</em><em>,</em><em> </em>while the traits of the adapted parents <em>do</em><em> </em>get passed down throughout generations, "fitness" does not necessarily refer to breeding and passing traits specifically, but rather, who lives and who dies (Natural Selection.)
I would say true. I say this because there have been times where scientists find out that there are better ways of performing experiments, or found that certain materials work better for certain tasks. (Especially true in medicinal fields!)
