Compact fluorescent bulbs are a more efficient way to provide electrical light within homes and other buildings. These bulbs are one of the easiest ways to save money. According to GE, compact flourescent bulbs, or CFLs for short, use 70% less energy than a traditional, incandescent bulb and last up to 10 times longer than a standard incandescent bulb. As society pushes for improved efficiency, compact flourescent bulbs need to be carefully examined. Although these bulbs are more efficient, there are many problems with compact fluorescent bulbs.
<span>It is a common misconception that elephants existed the same time as the dinosaurs did when in fact they have evolved 3 or 5 million years after these creatures.
The tusks of the elephant would probably be the structure not present in early elephants. It is only through evolution that these tusks grew. Some scientists have hypothesized that these tusks develop from the elephants' incisors.

The squirrels are attuned in their brains to understand that owls are a threat because it is a predator. This is visual stimuli that evolved over many years to elicit a conditioned response. This is an innate behavior (meaning that it has been pre-programmed into an animal's genes) and offspring are naturally born with it.
