explanations...

Just ponder this...

Five biologists by a pond. A frog leaps into the pond to escape a snake! The five then offer their "explanations" of what "caused" the frog to jump into the pond:

The Physiologist: "It is because the muscles in the frog's leg contract, following nerve impulses from the frog's brain".

The animal Behavior Scientist: "It is because the frog wants to avoid the snake and is pursuing a goal".

The Developmental Biologist: "The muscles and brain have become 'wired-up' during its life make these jumping actions happen when danger approaches".

An Evolutionary Biologist: "It is the result of adaptations during history, when frog's ancestors were selected by the ability to escape from snakes".

The Molecular Biologist steps up and, smiling sweetly, says that the other four are ALL WRONG!... "The frog jumps because of the biochemical properties of it muscles!"

In the next entry, five business consultants join the biologists. We will see what happen next...
