Most paleontologists hold that birds arelivingdinosaurs , the distant evolutionary descendants of animals like Tyrannosaurus king . Less clean , however , is how dinosaur evolved into the fowl we fuck today .

Audubon is currently running a feature article by Michael Balter about the oracular evolutionary history of modern birds , and the researchers working to uncover its mysteries . Evolutionary life scientist Ashley Heers , for example , study the biomechanics of later - date wench to see if their social movement at early stages of growth bear any resemblance to that of their distant ancestors :
She is using the latest telecasting and figurer moulding technology to canvass how baby birds develop the power to fly , looking for clues as to how dinosaurs evolve into dame — one of the most dramatic and successful evolutionary transformations in the history of life on earth .
“ Every clock time I wait at a razz , I am see a dinosaur , ” she says . “ That ’s what makes it exciting for me
Heers came to England fresh from doing a Ph.D. with Kenneth Dial at theUniversity of Montana ’s Flight Laboratoryin Missoula , Montana , probably the populace ’s leading inquiry center on bird aeronautics . In the course of action of her research , she has heap up considerable grounds that infant birds do indeed resemble the avian dinosaur antecedent , which had plumage but little if any ability to take flight . Thus at nine days old , her downy guinea domestic fowl chicks have very little wings and beam of light of crude - looking feathers still pervious to the line . Their tuft are simple and harmonious , lacking the complex structure of adult feathers , and the razz are too young to fly very far .
Heers takes one of the dame out of the composition board box and places it on an inclined base about a foot away . The skirt hesitates a second , then collect up its wings , and its courage , and jump back into the boxful . The video footage , captured on the data processor , shows that while the chick rely mostly on its legs to make the leap , it also flapped its wings between two and three time , adding just enough elevation to successfully bridge the gap . “ They ca n’t yet vanish very far , ” Heers says , “ but those tiny little wings are still very useful . ” This powerfully suggests , she contribute , that even if other dinos evolve plume for other intellect — to keep warm or for peacock - like intimate displays — they were already on their way of life to becoming birds .
Just how razzing - like were dinosaurs ? How dinosaur - alike are modern hiss ? of modern birds , and the researcher and biomechanics researchers . She is using the latest video and figurer modeling technology to analyze how baby birds rise the ability to fly , front for clues as to how dinosaurs evolve into birds — one of the most spectacular and successful evolutionary translation in the chronicle of life on ground .
In her doctoral dissertation , Heers draw comparability between the developmental biological science of modern birds and the evolutionary stages of dinosaurs that , over trillion of years , developed the capacitance for powered flight . The observation was initially run across with harsh criticism , but , over the last few years , Heers ’s and Dials ’s study has gain ground them “ respect and credibility , peculiarly from leading palaeontologist :
University of California - Berkeley researcher Kevin Padian , long a fan of Dial ’s and Heers ’s work , says the initial skepticism was totally off stand : “ This was exactly what was needed . ”
[ Stephen Brusatte , a paleontologist at the University of Edinburgh in the United Kingdom and a rising star in the paleontology world ] adds , “ Their work has been groundbreaking . They are learn living chick , and do n’t just meditate based on fossils . ” As for Heers , he tell , “ She ’s brilliant . She ’s not a traditional fossilist but a real ornithologist . ”
This is such a fun and compelling read . It ’s as much an evolutionary backgrounder as it is a profile of interesting paleontologists , most of whom arebasically rockstars , anyhow . Go read the rest of the Audubon small-arm for yourself .
