This document provides background information on Willi Hennig, the scientist known for introducing phylogenetic systematics. It describes that he was the firstborn son of a railroad worker and maid, grew up moving frequently with his family, and received encouragement towards science from a private tutor. As a young man, Hennig volunteered at a natural history museum where he was mentored by a curator and began publishing scientific works. The document aims to understand Hennig's personality and the influences that led to his revolutionary approach to systematics.
This review analyzes 214 published phylogeography studies of South American organisms to identify emerging patterns. The studies find striking genetic divergence among lineages, suggesting high undocumented diversity. Pleistocene climate oscillations and Pliocene/Miocene geological events shaped modern distributions in tropical and temperate regions. Herpetofauna diverged earlier than other groups. Forest species' ranges contracted more in glacial periods, while open habitat species responded variably to climate change. The results reveal a complex mosaic of phylogeography patterns across South America.
A l'occasion du premier Forum de l'Intelligence Artificielle organisé à Bordeaux en mars 2016 par Ascoergo, une projection du film Blade Runner a été faite. La question centrale du livre de K. Dick et du film de Scott est qu'est ce qu'un être humain ? Autrement dit l'intelligence artificielle dans son excellence pourra-t-elle devenir humaine?
Willi Hennig was born in 1913 in Germany to working class parents. He showed an early interest in natural history and worked at a natural history museum during his schooling. He received his PhD studying fly genitalia. Hennig began developing his ideas about phylogenetic systematics in the 1930s, emphasizing genealogical relationships and monophyly. His 1950 book formalized phylogenetic systematics, prioritizing shared derived characters over similarity. Though controversial, Hennig's approach revolutionized taxonomy by requiring classifications to reflect evolutionary history.
Sources Of Sexuality Related Information Among College Studentsandreademaria
The document summarizes a study that examined college students' sources of sexuality-related information, the topics they seek information about, and their perceived reliability of different information sources. The study found that college students most commonly get sexuality information from the internet (85%), friends (82%), and media (77%). Popular topics included contraceptives, pregnancy, STIs, and sexual health. Students viewed search engines and medical professionals as most reliable sources. The study provides insights that can help improve sexual health interventions and education for college students.
