to the study of Papuan ornithology; it furnishes a fresh starting point from which sub- sequent workers may undertake further studies” (Peters 1941). Ernst also published Systematics and the Origin of Species (1942) that shows “Certain aspects of speciation can be most advantageously developed from an ornithological approach” (Hubbs 1943) and this factor helps Ernst strengthen his work. In 1953‚ Ernst joined the Museum of Comparative Zoology (MCZ) at Harvard University where he taught undergraduate

Phylogenetics In biology‚ phylogenetics is the study of evolutionary relationships among groups of organisms (e.g. species‚populations)‚ which are discovered through molecular sequencing data and morphological data matrices. The term phylogenetics derives from the Greek terms phylé and phylon ‚ denoting "tribe"‚ "clan"‚ "race"] and the adjectival form‚ genetikós of the word genesis "origin"‚ "source"‚ "birth".The result of phylogenetic studies is a hypothesis about the evolutionary history of taxonomic

approximately 3.8 billion years ago. Repeated speciation and the divergence of life can be inferred from shared sets of biochemical and morphological traits‚ or by shared DNA sequences.[2] Thesehomologous traits and sequences are more similar among species that share a more recent common ancestor‚ and can be used to reconstruct evolutionary histories‚ using both existing species and the fossil record. Existing patterns of biodiversity have been shaped both by speciation and by extinction.[3]Charles Darwin was

Charles Darwin was a naturalist in the early 1800’s. He was born into a family full of scientists. But‚ when he failed to follow in his father’s footsteps‚ due to the fact that blood made him queasy‚ his father suggested he instead become a parson. Against his father’s wishes‚ he decided to study natural history. This lead him to his five-year voyage around the world on the HMS Beagle. On this voyage‚ Darwin studied and collected information on various species from around the world‚ allowing him

Dustin Moyer 1-18-15 Professor Obenson SCI 203 Phase 2 Lab Report Speciation The purpose of this lab is to discuss what would happen if a species within a population were suddenly split into two groups by an earthquake that creates a physical barrier such as a canyon. A species can grow into a large population. When this population is then split up by some type of natural occurrence‚ then one side must adapt to its new environment. So‚ the same population of species becomes a two completely
