Alligators have an extremely powerful bite. Alligators live in warm climates in lakes, ponds, swamps, and other slow-moving bodies of freshwater, but can also be found in marshes, and other brackish waters. Crocodilians retained many of the characteristics of the primitive archosaurs, such as a more complex skull with bones lost in avian evolution, a large body, and a more conserved body plan. To make the fluffiest mashed potatoes, boil up a starchier variety like Russets or bakers. As the ‘gator swam toward our small boat, we started the engine and quickly left the area.

If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! Avoid being near the water’s edge or swimming during this key feeding time. “What’s happening is the downstream genes lose, gain, or change binding sites for HOX [transcription factors].

You won’t hear it approaching. What actually happened?”. Sign up for daily emails to get the latest Harvard news.
Even though the alligator has short legs it can run quickly for short bursts, and has been known to climb chain link fences to avoid capture.

In the U.S., crocodiles are only found in southern Florida. “If you look at the entire archosaur branch, we have one of the most derived groups, birds, still around,” Abzhanov said. A … Be extra cautious during this time. Lifespan of alligators in the wild is about 35 years. They ensure, in effect, that the head goes at the top, the feet at the bottom, and everything else in the proper positions in between. Alligators are good pets. However, once they become accustomed to being fed by humans it loses its innate fear and will approach. HOX genes are so important in animal development that they’ve been highly conserved across millions of years of evolution.

Don’t assume alligators aren’t present because you don’t see one. That hasn’t always been the case, though, and that’s what attracts Arkhat Abzhanov. Alligators are beneficial to the environment.
The added complexity is not entirely unexpected, Abzhanov said. Still, alligators are large carnivorous predators that demand respect. HOX genes are called master genes because the transcription factors they produce control the functioning of many other genes. Teach your family about the alligator before venturing into their natural habitat. Birds, on the other hand, couldn’t be more different. Sign Up Today for More Access!

Seek medical help immediately for all injuries involving alligators.
Despite the very different developmental outcomes in birds and alligators, the genes themselves were expressed in pretty much the same domains in the two animals.
You really, really don’t want to be bitten by an alligator. This intriguing, scaly creature with a massive tail and an abundance of sharp teeth got its name from early Spanish explorers and settlers in Florida. Abzhanov is examining those genes and the effects of the proteins they produce, called transcription factors, to get at the root of those differences. One became modern crocodilians, and another dinosaurs. They are at the top of the food chain for a reason.

From an evolutionary standpoint, it makes more sense to alter the sensitivity of downstream genes to HOX transcription factors, changing a single gene at a time.

“It is a bit like building a house.
