Evolution of Birds It has become widely accepted that birds have evolved from reptiles in the Jurassic period and are the living descendants of a group of dinosaurs called theropods. Birds share hundreds of unique skeletal features with dinosaurs. Over the years‚ birds have evolved in a wide variety of forms‚ from flightless and aquatic to flying animals. Due to poor fossil records‚ some information regarding the evolution of birds are based on theories but during the last 30 years‚ the evolutionary

Evolution of penguins For this evolution project‚ I choose to research Penguins. The classification for this animal is as follows: K Neornithes‚ P Palaeognathae‚ C Neognathae‚ O Pelecaniformes‚ F Procellariformes‚ G Graviidae‚ S Spheniscidae. The first fossil penguin that was found‚ is today being held in the British Museum of Natural History. It was reportedly found by an anonymous Maori in New Zealand in 1859 and was named Palaeeudyptes Antarcticus despite the fact that the species

Evolution and classification Main article: Evolution of birds Archaeopteryx lithographica is often considered the oldest known bird The first classification of birds was developed by Francis Willughby and John Ray in their 1676 volume Ornithologiae.[5] Carolus Linnaeusmodified that work in 1758 to devise the taxonomic classification system currently in use.[6] Birds are categorised as the biological classAves in Linnaean taxonomy. Phylogenetic taxonomy places Aves in the dinosaur clade Theropoda

Human Evolution Human Evolution‚ the biological and cultural development of the species Homo sapiens‚ or human beings. A large number of fossil bones and teeth have been found at various places throughout Africa‚ Europe‚ and Asia. Tools of stone‚ bone‚ and wood‚ as well as fire hearths‚ campsites‚ and burials‚ also have been discovered and excavated. As a result of these discoveries‚ a picture of human evolution during the past 4 to 5 million years has emerged. Human Physical Traits Humans are

Introduction To Evolution What is Evolution? Evolution is the process by which all living things have developed from primitive organisms through changes occurring over billions of years‚ a process that includes all animals and plants. Exactly how evolution occurs is still a matter of debate‚ but there are many different theories and that it occurs is a scientific fact. Biologists agree that all living things come through a long history of changes shaped by physical and chemical processes that

Human evolution is the biological and cultural development of humans. A human is any member of the species Homo sapiens‚ meaning "wise man." Since at least the Upper Paleolithic era‚ some 40‚000 years ago‚ every human society has devised a creation myth to explain how humans came to be. Creation myths are based on cultural beliefs that have been adopted as a legitimate explanation by a society as to where we came from. The science of paleoanthropology‚ which also tries to create a narrative about

Evolution of the Alligator Evolution of the Alligator One of the most highly evolved animals on the Earth today is the alligator. Found mainly in the swamps and warmer climates of the earth‚ these predators are one of the few animals left that existed when the dinosaurs roamed the planet. Over the millennia‚ they have evolved into one of the most feared and interesting creatures today. However‚ the modern alligator is a far cry from its ancestral roots. Today‚ by looking at the anatomy of

intelligence is very difficult. Many theories have been posed as selective mechanisms for the trends toward increased intelligence in primate evolution. Some emphasize complex ecological pressures‚ mainly foraging strategies as the primary forces driving an evolutionary increases in cognitive abilities‚ and other suggest that increased social complexity favored the evolution of primate intelligence (Tomasello and Call‚ 1997). Across the animal kingdom‚ brain size increases with increasing body size‚ however
