Vor einem Tag · Gustav Mahler ( German: [ˈɡʊstaf ˈmaːlɐ]; 7 July 1860 – 18 May 1911) was an Austro-Bohemian Romantic composer, and one of the leading conductors of his generation. As a composer he acted as a bridge between the 19th-century Austro-German tradition and the modernism of the early 20th century. While in his lifetime his status as a ...

The classification of living things into animals and plants is an ancient one. Aristotle (384–322 BC) classified animal species in his History of Animals, while his pupil Theophrastus (c.371–c.287 BC) wrote a parallel work, the Historia Plantarum, on plants. Carl Linnaeus (1707–1778) laid the foundations for modern biological nomenclature, now regu...
In 1674, Antonie van Leeuwenhoek, often called the "father of microscopy", sent the Royal Societyof London a copy of his first observations of microscopic single-celled organisms. Until then, the existence of such microscopic organisms was entirely unknown. Despite this, Linnaeus did not include any microscopic creatures in his original taxonomy. A...
The development of microscopy revealed important distinctions between those organisms whose cells do not have a distinct nucleus (prokaryotes) and organisms whose cells do have a distinct nucleus (eukaryotes). In 1937 Édouard Chattonintroduced the terms "prokaryote" and "eukaryote" to differentiate these organisms. In 1938, Herbert F. Copeland prop...
The differences between fungi and other organisms regarded as plants had long been recognised by some; Haeckel had moved the fungi out of Plantae into Protista after his original classification, but was largely ignored in this separation by scientists of his time. Robert Whittaker recognized an additional kingdom for the Fungi. The resulting five-k...
In 1977, Carl Woese and colleagues proposed the fundamental subdivision of the prokaryotes into the Eubacteria (later called the Bacteria) and Archaebacteria (later called the Archaea), based on ribosomal RNA structure; this would later lead to the proposal of three "domains" of life, of Bacteria, Archaea, and Eukaryota. Combined with the five-king...
Thomas Cavalier-Smith supported the consensus at that time, that the difference between Eubacteria and Archaebacteria was so great (particularly considering the genetic distance of ribosomal genes) that the prokaryotes needed to be separated into two different kingdoms. He then divided Eubacteria into two subkingdoms: Negibacteria (Gram-negative ba...
Cavalier-Smith and his collaborators revised their classification in 2015. In this scheme they introduced two superkingdoms of Prokaryota and Eukaryota and seven kingdoms. Prokaryota have two kingdoms: Bacteria and Archaea. (This was based on the consensus in the Taxonomic Outline of Bacteria and Archaea, and the Catalogue of Life). The Eukaryota h...
The kingdom-level classification of life is still widely employed as a useful way of grouping organisms, notwithstanding some problems with this approach: 1. Kingdoms such as Protozoa represent grades rather than clades, and so are rejected by phylogenetic classificationsystems. 2. The most recent research does not support the classification of the...
Vor einem Tag · The entire right field grandstand collapsed in 1926, forcing the Phillies to move to the A's Shibe Park (five blocks west on Lehigh Avenue from Baker Bowl) for 1927. The Phillies tried to move to Shibe Park on a permanent basis as tenants of the A's. However, Baker Bowl's owner, Charles W. Murphy, at first refused to let the Phillies out of their lease. He finally relented in 1938, and only ...
