Birds evolved from reptiles millions of years ago and they still share many common features today. For example the most obvious one is that both reptiles and birds lay eggs. They also have a very similar physiology, in particular a fact that they both have...

Zoology is the discipline of biology that involves the study of animals. Historically, an important difference is between zoology in pre-Darwinian and post-Darwinian times with Charles Darwin's theory of evolution by natural selection now fundamental to the discipline. Before Darwin came along in the 19th...

Newsflash:"Paleontologists have used upright walking (bipedalism) as a marker defining the line between humans and apes. The popular "Savannah hypothesis" held that the ancestors to chimps, gorillas and humans moved from the trees to the ground, where they walked on all fours.Orangutans walk upright...

Stem cell research has been moving right along towards more uses and aids to medicine and disease control. The uses for stem cells are as limited as the areas they will regenerate. Any cell in the human body can be copied by a stem cell...
