Hybridisation (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different variety (botany), varieties, subspecies, species or genus, genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera (genetics), chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show Heterosis, hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductive isolation, reproductively isola ...

Harvard Faculty Of Arts And Sciences
The Harvard Faculty of Arts and Sciences (FAS) is the largest of the ten faculties that constitute Harvard University. Headquartered principally in Cambridge, Massachusetts, and centered in the historic Harvard Yard, FAS is the only faculty responsible for both undergraduate and graduate education. FAS administers the courses offered at Harvard College, the Harvard Kenneth C. Griffin Graduate School of Arts and Sciences, Kenneth C. Griffin Graduate School of Arts and Sciences, the Harvard John A. Paulson School of Engineering and Applied Sciences, John A. Paulson School of Engineering and Applied Sciences (SEAS), and the Harvard Division of Continuing Education. It was headed by interim dean Emma Dench until August 1, 2023, when Hopi Hoekstra became Dean of FAS. As of Fall 2019, FAS comprised 1221 total faculty, including 719 tenured and tenure-track professors as well as 502 other professors, lecturers, preceptors, and visiting faculty in some 30 academic departments in the arts ...

Dean (education)
Dean is a title employed in academic administrations such as colleges or universities for a person with significant authority over a specific academic unit, over a specific area of concern, or both. In the United States and Canada, deans are usually university professors who serve as the heads of a university's constituent colleges and schools. Deans are common in private preparatory schools, and occasionally found in middle schools and high schools as well. Origin A "dean" (Latin: '' decanus'') was originally the head of a group of ten soldiers or monks. Eventually an ecclesiastical dean became the head of a group of canons or other religious groups. When the universities grew out of the cathedral schools and monastic schools, the title of dean was used for officials with various administrative duties. Use Bulgaria and Romania In Bulgarian and Romanian universities, a dean is the head of a faculty, which may include several academic departments. Every faculty unit of u ...

Evolutionary Biology
Evolutionary biology is the subfield of biology that studies the evolutionary processes such as natural selection, common descent, and speciation that produced the diversity of life on Earth. In the 1930s, the discipline of evolutionary biology emerged through what Julian Huxley called the Modern synthesis (20th century), modern synthesis of understanding, from previously unrelated fields of biological research, such as genetics and ecology, systematics, and paleontology. The investigational range of current research has widened to encompass the genetic architecture of adaptation, molecular evolution, and the different forces that contribute to evolution, such as sexual selection, genetic drift, and biogeography. The newer field of evolutionary developmental biology ("evo-devo") investigates how embryogenesis is controlled, thus yielding a wider synthesis that integrates developmental biology with the fields of study covered by the earlier evolutionary synthesis. Subfields ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hopi Hoekstra
Danielle "Hopi" Elisabeth Hoekstra (born 1972) is an evolutionary biologist working at Harvard University in Cambridge, Massachusetts, where she is Dean of the Harvard Faculty of Arts and Sciences. Her lab uses natural populations of rodents to study the genetic basis of adaptation. She is the C.Y. Chan Professor of Arts and Sciences and the Xiaomeng Tong and Yu Chen Professor of Life Sciences in the Department of Organismic and Evolutionary Biology and the Department of Molecular and Cellular Biology at Harvard University. She is also the Curator of Mammals at the Museum of Comparative Zoology and a Harvard College Professor. In 2014, Hoekstra became a Howard Hughes Medical Institute Investigator. In 2016, she was elected to the National Academy of Sciences, and in 2017, she was elected to the American Academy of Arts and Sciences. Hoekstra became the Edgerley Family Dean of Harvard's Faculty of Arts and Sciences in August 2023. Early life Hoekstra was born to a family of Dutch a ...

Linnean Society Of London
The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and Taxonomy (biology), taxonomy. It possesses several important biological specimen, manuscript and literature collections, and publishes academic journals and books on plant and animal biology. The society also awards a number of prestigious medals and prizes. A product of the Age of Enlightenment, 18th-century enlightenment, the society is the oldest extant biological society in the world and is historically important as the venue for the first public presentation of the theory of evolution by natural selection on 1 July 1858. The patron of the society is Anne, Princess Royal. Honorary members include: King Charles III of the United Kingdom, Emeritus Emperor Akihito of Japan, King Carl XVI Gustaf of Sweden (both of the latter have active interests in natural history), and the eminent naturalist and broadcaster Sir David Attenboroug ...

Speciation
Speciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages. Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book ''On the Origin of Species''. He also identified sexual selection as a likely mechanism, but found it problematic. There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another: allopatric speciation, allopatric, peripatric speciation, peripatric, parapatric speciation, parapatric, and sympatric speciation, sympatric. Whether genetic drift is a minor or major contributor to speciation is the subject of much ongoing discussion. Rapid sympatric speciation can take place through polyploidy, such as by doubling of chromosome number; the result is progeny wh ...
