The evolution of birds began in the Jurassic Period, with the earliest birds derived from a clade of theropoda dinosaurs named Paraves. Birds are categorized as a biological class, Aves.For more than a century, the small theropod dinosaur Archaeopteryx lithographica from the Late Jurassic period was considered to have been the earliest bird. Modern phylogenies place birds in the dinosaur clade.

Although birds’ eggs are generally ovoid in shape. the average egg length (light blue), asymmetry (medium blue), and ellipticity (dark blue) are represented by line lengths at branch tips.

Are Birds Really Dinosaurs? Ask your average paleontologist who is familiar with the phylogeny of vertebrates and they will probably tell you that yes, birds (avians) are dinosaurs.Using proper terminology, birds are avian dinosaurs; other dinosaurs are non-avian dinosaurs, and (strange as it may sound) birds are technically considered reptiles.

Misconceptions about evolutionary theory and processes. MISCONCEPTION: Evolution is a theory about the origin of life. CORRECTION: Evolutionary theory does encompass ideas and evidence regarding life’s origins (e.g., whether or not it happened near a deep-sea vent, which organic molecules came first, etc.), but this is not the central focus of evolutionary theory.

Vertebrate animals have come a long way since their tiny, translucent ancestors swam the world’s seas over 500 million years ago. The following is a roughly chronological survey of the major vertebrate animal groups, ranging from fish to amphibians to mammals, with some notable extinct reptile lineages (including archosaurs, dinosaurs, and pterosaurs) in between.

Welcome to the study of reptile evolution – Here you’ll be able to trace the lineage of major clades, including the line that ultimately led to humans.You’ll see where and when body parts (= traits) became added, substracted and modified. Most of the evolutionary links have been made and many of the mysteries and mistakes of the past have been solved and corrected with the large reptile tree.
