There are many reasons to why slaves were essential in the colonial economy:
Slaves were generally used more in the south, because large plantations were found there, which meant that the need for large amounts of workers.
Slaves provided cheap labors, and as they were not "citizens" of the US, they were not allowed their rights.
Slaves were also relatively easy to buy and replace, however, their survival rates were not that good after they traveled long distance.

The guppies evolved at a rate between 3700 and 45,000 Darwin's. For comparison, artificial-selection experiments on mice show rates of up to 200,000 Darwin's while most rates measured in the fossil record are only 0.1 to 1.0 Darwin.
Guppies introduced to a low-predation environment adapted to their new environment by producing larger and fewer offspring with each reproductive cycle. No such adaptation was seen in guppies that colonized a high-predation
With each generation, more guppies passed on the gene for small spots to their offspring. The rocks became smaller. More guppies with small spots survived long enough to pass on the gene for small spots to their offspring the rocks became smaller.

There are several precautions that should be taken during catastrophic weather. In the case of a hurricane warning two precautions you should take immediately are:
1. Fortifying your house: In doing this you give your home the utmost care and protection needed to give it the best chance to minimize damage.
2. Evacuate: This is more or less common sense. whenever there is a massive storm most evacuations are mandatory. Regardless whenever a storm is likely to hit your area it is best to pack up pets and all essentials and head for the safest area as quickly as possible. waiting till the last minute could get you stuck in traffic causing you to be caught in your car during the store which is more dangerous than remaining in your own house.
