Zoologists and biologists love it when an animal turns up where it was n’t expected to . Either some unbelievable migration outcome has happen – perhaps involve aprison break – or a Modern metal money has been discover .
In the case of the latter , the newfound metal money can sometimes look a little like one of its evolutionary cousins . Writing inThe American Naturalist , a University of Toronto ( UT)-led team describes a new uncovering of its own , but in this casing , the mark unexampled lizard looks almost superposable to another one found far aside , despite the fact that both are exclusively dissimilar coinage .
This chamaeleon - like lounge lizard , Anolis landestoyi , was first spotted and shoot on the island of Hispaniola , a strip of territory shared by Haiti and the Dominican Republic . At first coup d’oeil , it appeared to be the same type of lizard found in Cuba , theAnolis porcus . “ Our immediate thought was that this looks like something that ’s suppose to be in Cuba , not in Hispaniola , ” Luke Mahler , the study ’s spark advance author and an assistant professor of development and bionomics at UT , say in astatement .
After one was captured by natural scientist Miguel Landestoy , he mail vindicated picture of it to UT researcher . They noted that it was slenderly morphologically different to its Cuban cousin , mean that it was indeed a disjoined species of lizard . “ I always wanted to key a novel coinage , ” Mahler added . “ Doing so is the fulfilment of a dreaming I ’ve had since I was a little kid . ”
As it turn out , these type of lounge lizard – Greater Antillean anoles – are found all across these islands . They are a Graeco-Roman instance of something fuck as retroflex adaptive radiation , wherein related coinage evolving on different island finally specialise into similar species with similar word structure , for occupy similar ecological niches . They are known as “ ecomorphs . ”

Most nifty Antillean anoles in reality have a matching counterpart on another island , although about a 5th presently do not . This raw find strike another off that more and more little lean .
The newly discoveredA. landestoyi , like its Cuban cousin , resemble chamaeleon rather than distinctive Anolis carolinensis in that they ’re rather vast , slow - impress , and party favour cleave on to moss- or lichen - coated branches high up in the canopy of the timber .
As for how this species evolve , there are two options : The first is thatA. landestoyihas a shared line of descent with the CubanA. porcus , whose predecessor migrated to Hispaniola from Cuba . The second choice is that this is a instance ofconvergent evolution , wherein distally related organisms evolve the same adaptations in different environments . Either way , species across these island are more similar than the squad previously opine .
unhappily , despite being a freshly identified metal money , it is already in considerable fuss . It occupies a home ground that is live fanatic deforestation , and time is running out to save it from certain experimental extinction .
