Luís Wittnich Carrisso
Luís Wittnich Carrisso (14 February 1886 – 14 June 1937) was a Portuguese botanist, professor at the University of Coimbra. Carrisso was born in Figueira da Foz.Sara Graca da Silva; Fatima Vieira; Jorge Bastos da Silva. ''(Dis)Entangling Darwin: Cross-disciplinary Reflections on the Man and His Legacy''. Cambridge Scholars Publishing. pp. 105-110. He attended the Faculty of Philosophy of University of Coimbra (1904-1910). After graduating he became a student of botanist Julio Augusto Henriques. Carrisso took interest in evolution and heredity and presented his PhD thesis ''Hereditariedade'' in 1911. He published scientific work on ecology and plant systematics. In 1918, he became Professor of Botany at University of Coimbra's Botanical Garden. He was a supporter of Charles Darwin's theory of evolution but was skeptical of the role of natural selection. He embraced mutationism. He died on 6 June 1937 in the Namib desert (Moçâmedes), in Angola, of cardiac syncope, durin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jardim Botânico Da Universidade De Coimbra
The Botanical Garden of the University of Coimbra ( or simply ''Jardim Botânico'') is a botanical garden in Coimbra, Portugal. History It was founded in 1772 by Sebastião José de Carvalho e Melo (the Marquis of Pombal). The location for the ''Hortus Botanicus''—part of the farm of S. Bento's College in the Ursulinas Valley—was chosen by the vice-chancellor of the University of Coimbra (Francisco de Lemos). Domingos Vandelli was the first supervisor for the orientation of the garden, followed in 1791 by Félix Avelar Brotero, professor of Botany and Agriculture. The botanist Luís Wittnich Carrisso, from the year he became a full professor, from 1918 until the date of his death in 1937, enriched the Garden with new plants, namely with exotic African plants, most of them originating in Angola. He developed relations with similar gardens, promoting exchanges of seeds and plants, reinforcing the offer in the publication of ''Index Seminum'', which, at the time, was consid ...

Natural Selection
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with selective breeding, artificial selection, which in his view is intentional, whereas natural selection is not. Genetic diversity, Variation exists within all populations of organisms. This occurs partly because random mutations arise in the genome of an individual organism, and their offspring can inherit such mutations. Throughout the lives of the individuals, their genomes interact with their environments to cause variations in traits. The environment of a genome includes the molecular biology in the Cell (biology), cell, other cells, other individuals, populations, species, as well as the abiotic environment. Because individuals with certain variants of the trait tend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mutationism
Mutationism is one of several alternatives to evolution by natural selection that have existed both before and after the publication of Charles Darwin's 1859 book ''On the Origin of Species''. In the theory, mutation was the source of novelty, creating new forms and new species, potentially instantaneously, in sudden jumps. This was envisaged as driving evolution, which was thought to be limited by the supply of mutations. Before Darwin, biologists commonly believed in saltationism, the possibility of large evolutionary jumps, including immediate speciation. For example, in 1822 Étienne Geoffroy Saint-Hilaire argued that species could be formed by sudden transformations, or what would later be called macromutation. Darwin opposed saltation, insisting on gradualism in evolution as geology's uniformitarianism. In 1864, Albert von Kölliker revived Geoffroy's theory. In 1901 the geneticist Hugo de Vries gave the name "mutation" to seemingly new forms that suddenly arose in his exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Figueira Da Foz
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form " people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural ...

Namib
The Namib ( ; pt, Namibe) is a coastal desert in Southern Africa. The name is of Khoekhoegowab origin and means "vast place". According to the broadest definition, the Namib stretches for more than along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to inland to the foot of the Great Escarpment. Annual precipitation ranges from in the most arid regions to at the escarpment, making the Namib the only true desert in southern Africa. Having endured arid or semi-arid conditions for roughly 55–80 million years, the Namib may be the oldest desert in the world and conta ...

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plant Systematics
The history of plant systematics—the biological classification of plants—stretches from the work of ancient Greek to modern evolutionary biologists. As a field of science, plant systematics came into being only slowly, early plant lore usually being treated as part of the study of medicine. Later, classification and description was driven by natural history and natural theology. Until the advent of the theory of evolution, nearly all classification was based on the scala naturae. The professionalization of botany in the 18th and 19th century marked a shift toward more holistic classification methods, eventually based on evolutionary relationships. Antiquity The peripatetic philosopher Theophrastus (372–287 BC), as a student of Aristotle in Ancient Greece, wrote ''Historia Plantarum'', the earliest surviving treatise on plants, where he listed the names of over 500 plant species.''Concise Encyclopedia Of Science And Technology'', McGraw-Hill He did not articula ...
