Alfred Romer and the Evolution of Vertebrae

Alfred Romer and the Evolution of Vertebrae

On December 28, 1894, American paleontologist and biologist Alfred Sherwood Romer was born. Romer was a a specialist in vertebrate evolution. He studied the evolution of early vertebrates in biological terms of comparative anatomy and embryology. He researched muscle and limb evolution, the development and evolutionary history of cartilage and bone, and the structure and function of the nervous system. Youth and Education Alfred Romer was born in White Plains, New York,…

Evolution is not Reversible – Louis Dollo

Evolution is not Reversible – Louis Dollo

On December 7, 1857, French-born Belgian palaeontologist Louis Dollo was born. Dollo is best known for his work on dinosaurs. He also posited that evolution is not reversible, known as Dollo’s law. Together with the Austrian Othenio Abel, Dollo established the principles of paleobiology. Early Years Louis Dollo was born in Lille, Nord-Pas-de-Calais. At the École Centrale de Lille, Dollo studied with the Jules Gosselet and the zoologist Alfred Giard. In 1877, Louis…

The Discovery of the Taung Child

The Discovery of the Taung Child

On November 28, 1924, workers at the Buxton Limeworks near Taung, South Africa, showed a fossilised primate skull to Raymond Dart, an Australian anatomist and anthropologist, who described it as a new species in the journal Nature in 1925. The fossil was soon nicknamed the Taung Child and the new species was named Australopithecus africanus – the “southern ape from Africa” – and described by Dart as “an extinct race of apes…

The so-called Mauer 1 mandible is the oldest fossilized specimen of the genus Homo ever to be discovered in Germany. The Mauer 1 mandible is the type specimen of the species Homo heidelbergensis, a subspecies of Homo erectus. In 1907, Daniel Hartmann unearthed a mandibular in a…

Edward Drinker Cope and the Neo-Lamarckian School of Thought

Edward Drinker Cope and the Neo-Lamarckian School of Thought

On July 28, 1840, American paleontologist and comparative anatomist Edward Drinker Cope was born. Being s well as a noted herpetologist and ichthyologist, he was a founder of the Neo-Lamarckism school of thought. This school believed that changes in developmental (embryonic) timing, not natural selection, was the driving force of evolution. Cope thought that groups of species that shared similar developmental patterns could be grouped into more inclusive groups (i.e. genera, families,…
