This is evolution at work. It is not about creating a new creature, but a more environment oriented species. The fact the female lays less eggs, and has larger babies is an evolution of the DNA that controls the production of eggs. Its a clear change to respond to the environment surrounding it.
Adaptation, on the other hand, doesn't involve changing the basic DNA of a creature, but also works in the circumstances surrounding it. For example: During seasons of heavy snows and lots of moisture, deer have a tendency to have 2-3 foals, during high periods of drought, they tend to have 1 or none.
The two examples given here are different exactly how????? I call BS.
Eight years later (less than 30 guppy generations), the researchers found that the guppies in the low-predation environment above the barrier waterfall had adapted to their new environment by producing larger and fewer offspring with each reproductive cycle. No such adaptation was seen in the guppies that colonized the high-predation environment below the barrier waterfall.
So, the article uses the term Adaptation - where's the fire?
