21 de abr. de 2008 · Italian wall lizards introduced to a tiny island off the coast of Croatia are evolving in ways that would normally take millions of years to play out, new research shows.
Lizards in an Evolutionary Tree is one of three films in HHMI’s Origin of Species collection. This film describes how the more than 700 islands of the Caribbean are home to about 150 species of anoles, a closely related group of lizards (genus Anolis) that occupy diverse habitats and niches.
The main points to the transition from reptile to bird are the evolution from scales to feathers, the evolution of the beak (although independently evolved in other organisms), the hallofication of bones, development of flight, and warm-bloodedness.
12 de jun. de 2024 · Reptile - Evolution, Paleontology, Adaptation: The first land vertebrates, the Tetrapoda, appeared near the middle of the Devonian Period. The earliest known reptiles, Hylonomus and Paleothyris, date from the Late Carboniferous.
6 de oct. de 2020 · New study by a team of Harvard-led researchers rebuts 75-year-old belief in their evolution. Challenging a 75-year-old notion about how and when reptiles evolved during the past 300 million-plus years involves a lot of camerawork, loads of CT scanning, and, most of all, thousands of miles of travel.
27 de feb. de 2024 · Evidence of evolutionary trends in lizards can be observed in species’ physical characteristics, behavioral patterns, and genetic makeup. By analyzing populations of lizards over generations, scientists have detected changes in traits such as body size, coloration, and reproductive strategies.
12 de nov. de 2013 · This film explores the adaptation of anole lizards (genus Anolis) to habitats common across the islands of the Caribbean. The anoles are excellent examples of adaptive radiation, convergent evolution, and speciation through reproductive isolation.
