3 leg lizard can develop against all difficulties, about the challenging assumptions about how evolution works in wild

We are a lizard biologist, and we need to catch lizards to do our job.

Years ago, one of us was in the Bahamas, who chased the unmarried lizards usually across the dense and tight branches, disappointed that his fervor was thwarting his efforts to catch him. Only when we caught, we found out that the entire left left leg of this Valley Brown Anval was missing. This amazing observation set our research on an unexpected way.

Due to the encounter of this opportunity, we were forced to cooperate with more than 60 peers around the world to do what we suspect that this could be a wider trend. Our research revealed 122 incidents of organ damage in 58 lizard species and revealed that these “three -foot pirates” – rare survivors of traumatic injuries can also run faster, maintain healthy body weight, successfully re -lived life. Has appeared in paper American nature Journal.

Clearly, most lizards may not be able to escape such catastrophic injuries. The documents we are making are extraordinary cases that refuse our expectations about natural choice.

This discovery is shocking because the organs of the lizard represent one of the most studied examples of the biology of evolutionary adaptation. For decades, scientists have proven that even a small difference in the length of the leg between individual lizards can mean the difference between life and death – affecting their ability to avoid hunters, catching hunting and finding peers.

Since subtle variations are very important, biologists have long been assumed that losing the entire organs should be disastrous.

Yet our global survey tells a different story about these remarkable survivors. Working with colleagues in six continents, we found lizards infected with organs in almost all large lizard families, ranging from small gacoos to large -scale ages.

Whatever the trauma of these animals caused their injuries, it was clearly healed. Perhaps the most notable thing is that we document the loss of organs that survived in the chameleon, even in the chameleon, the mounted experts on the trees whose movement requires perfect harmony of the organs.

Promoted, not just alive

The physical condition of these lizards was amazing. Instead of being a nutrition, many organs affected by the organs were actually heavier than their size, which shows that they are looking for a success in spite of their disability. Some were actively reproducting, women who were successfully witnessed to connect eggs and men carrying men.

These results force us to revise some of the basic assumptions on how evolution in the wild population can work. Charles Darwin imagined the natural choice as a proportional force, every feature “checking daily and hour”.

But perhaps the choice is more epic than permanent. The length of the organs may be of paramount importance, while during other times-such as when food is lacking and hunters are lacking, the length of the length decreases and three feet lizards can flourish.

These lizards offer incredible solutions that have been created by millions of years in their biology. Instead of being inactive for their injuries, they can survive by choosing lizard safe residence or hunting strategies, using smart behavior to avoid situations where their disability will have a loss.

Biological engineering in the process

Our research connects the observations of the natural history of the old -fashioned, with a modern, bio -mechanical analysis.

We use high -speed cameras and computer software that can track the Movement Frame through the frame to analyze the naked eye -hidden -hidden mechanics. This combination of field biology and laboratory health allows us only to understand that these lizards survive, but how they perform this remarkable feat.

When we experienced the athletic performance of the three -foot lizards, the results denied expectations. Some animals were clearly damaged in their spraying abilities, but others really racked up at a 2 -meter dash during our “lizard Olympics” than the same size.

High -speed video analysis revealed their secrets: Fast living survivors pay through creative bio -mechanical solutions. A brown molecule has dramatically increased its previous organs while losing half of the organs, using exaggerated cinnamic movements to compensate for the lost leg.

Unexpected – by documenting the seemingly impossible survivors, we have been reminded that nature is still surprised that we can basically change how we think about life ourselves.
