The Development History of Biogeography

Biogeography is a major branch of geography, often considered a subdivision of physical geography. This paper is a qualitative review of the historical perspective of its development. Although there

HAECKEL ' S Kingdom Protista and Current Concepts in Systematic

The author briefly presents his own skeletal arrangement of high-level protistan taxa that may be an improvement over those in the recent literature, with emphasis on the idea that the diversity of the protists is too great to be confined to a single kingdom and, thus, that their species require dispersal throughout all of the several kingdoms of the eukaryotic biotic world that are becoming widely recognized today.

Not plants or animals: a brief history of the origin of Kingdoms Protozoa, Protista and Protoctista.

In the wake of Darwin's evolutionary ideas, mid-nineteenth century naturalists realized the shortcomings of the long established two-kingdom system of organismal classification and introduced concepts of additional kingdoms (Protozoa, Protista, Protoctista, etc.) to accommodate the nature of these organisms as not true plants or animals.

Phylogeny and Megasystematics of Phagotrophic Heterokonts (Kingdom Chromista)

Four new biciliate bicoecean genera and five new species are described and the zooflagellate class Bicoecea (perhaps the ancestral phenotype of Bigyra) is unexpectedly diverse and a major focus of this study.

A Phylogenomic Framework to Study the Diversity and Evolution of Stramenopiles (=Heterokonts).

The first extensive phylogenomic analysis of stramenopiles, including representatives of most major lineages, provides a robust phylogenetic framework to investigate the evolution and diversification of this group of ecologically relevant protists.

Phylogeny and beyond: Scientific, historical, and conceptual significance of the first tree of life

The way in which this monumental discovery was made, its context within the historical development of evolutionary thought, and how it has impacted the authors' understanding of the emergence of life and the characterization of the evolutionary process in its most general form are described.

The neomuran origin of archaebacteria, the negibacterial root of the universal tree and bacterial megaclassification.

The origin from a drastically altered actinobacterium of neomura, and the immediately subsequent simultaneous origins of archaebacteria and eukaryotes, are the most extreme and important cases of quantum evolution since cells began.

Multidomain ribosomal protein trees and the planctobacterial origin of neomura (eukaryotes, archaebacteria)

Unique presence of key pre-neomuran characters favours Planctobacteria only as ancestral to neomura, which apparently arose by coevolutionary repercussions (explained here in detail, including RP replacement) of simultaneous outer membrane and murein loss.

How many kingdoms of life? Eukaryotic phylogeny and philosophy of systematics

The debate and analyze the pros and cons of both Hennigian principles and bunch small, relatively uncharacteristic groups into paraphyletic taxa, creating systems that are more convenient are presented.

Problems of taphonomy and sampling adequacy hinder direct evolutionary interpretations of pattern in the Precambrian paleontological record; however, molecular studies of microbial phylogeny and

Eubacteria, halobacteria, and the origin of photosynthesis: the photocytes.

The data indicate that together the eubacteria and the halobacteria form a monophyletic group for which the name "photocytes" is proposed, and if other techniques of phylogenetic analysis confirm this evolutionary tree, it is proposed that the photocytes be given urkingdom status.
