Helen Spurway
Helen Spurway (12 June 1915 – 15 February 1978) was a British biologist and the second wife of J. B. S. Haldane. She emigrated to India in 1957 along with him and conducted research in field biology with Krishna Dronamraju, Suresh Jayakar, and others. Sometimes known as Helen Spurway-Haldane. Life and career Spurway was born in 1915 in the London borough of Wandsworth, the daughter of Frank Spurway and Kate Lea, who were employees of the Post Office, as a telegraphist and a telegraphist and postal clerk. She obtained her Ph.D. in genetics in 1938 at University College London under the supervision of Haldane, whom she met as an undergraduate and married in 1945. Her early research was in the genetics of ''Drosophila subobscura'', but later switched to the reproductive biology of the guppy, ''Lebistes reticulatus''. Her claim, in 1955, that parthenogenesis, which occurs in the guppy in nature, may also occur (though very rarely) in the human species, leading to so-called "virgin b ...

Biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypotheses. Their discoveries may have applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans. In modern times, most biologists have one or more academic degrees such as a bachelor's degree plus an advanced degree like a master's degree or a doctorate. Like other scientists, biologists can be fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Ernst Mayr
Ernst Walter Mayr (; 5 July 1904 – 3 February 2005) was one of the 20th century's leading evolutionary biologists. He was also a renowned Taxonomy (biology), taxonomist, tropical explorer, ornithologist, Philosophy of biology, philosopher of biology, and History of science, historian of science. His work contributed to the conceptual revolution that led to the Modern synthesis (20th century), modern evolutionary synthesis of Gregor Mendel, Mendelian genetics, systematics, and Charles Darwin, Darwinian evolution, and to the development of the Species, biological species concept. Although Charles Darwin and others posited that multiple species could evolve from a single common ancestor, the mechanism by which this occurred was not understood, creating the ''species problem''. Ernst Mayr approached the problem with a new definition for species. In his book ''Systematics and the Origin of Species'' (1942) he wrote that a species is not just a group of Morphology (biology), morph ...

Salim Ali
Sálim Moizuddin Abdul Ali (12 November 1896 – 20 June 1987) was an Indian ornithologist and naturalist. Sometimes referred to as the "''Birdman of India''", Salim Ali was the first Indian to conduct systematic bird surveys across India and wrote several bird books that popularized ornithology in India. He became a key figure behind the Bombay Natural History Society after 1947 and used his personal influence to garner government support for the organisation, create the Bharatpur bird sanctuary (Keoladeo National Park) and prevent the destruction of what is now the Silent Valley National Park. Along with Sidney Dillon Ripley he wrote the landmark ten volume '' Handbook of the Birds of India and Pakistan'', a second edition of which was completed after his death. He was awarded the Padma Bhushan in 1958 and the Padma Vibhushan in 1976, India's third and second highest civilian honours respectively. Several species of birds, Salim Ali's fruit bat, a couple of bird sanct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Konrad Lorenz
Konrad Zacharias Lorenz (; 7 November 1903 – 27 February 1989) was an Austrian zoologist, ethologist, and ornithologist. He shared the 1973 Nobel Prize in Physiology or Medicine with Nikolaas Tinbergen and Karl von Frisch. He is often regarded as one of the founders of modern ethology, the study of animal behavior. He developed an approach that began with an earlier generation, including his teacher Oskar Heinroth. Lorenz studied instinctive behavior in animals, especially in greylag geese and jackdaws. Working with geese, he investigated the principle of imprinting, the process by which some nidifugous birds (i.e. birds that leave their nest early) bond instinctively with the first moving object that they see within the first hours of hatching. Although Lorenz did not discover the topic, he became widely known for his descriptions of imprinting as an instinctive bond. In 1936 he met Tinbergen, and the two collaborated in developing ethology as a separate sub-discipline ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orissa
Odisha (English: , ), formerly Orissa ( the official name until 2011), is an Indian state located in Eastern India. It is the 8th largest state by area, and the 11th largest by population. The state has the third largest population of Scheduled Tribes in India. It neighbours the states of Jharkhand and West Bengal to the north, Chhattisgarh to the west, and Andhra Pradesh to the south. Odisha has a coastline of along the Bay of Bengal in Indian Ocean. The region is also known as Utkala and is also mentioned in India's national anthem, "Jana Gana Mana". The language of Odisha is Odia, which is one of the Classical Languages of India. The ancient kingdom of Kalinga, which was invaded by the Mauryan Emperor Ashoka (which was again won back from them by King Kharavela) in 261 BCE resulting in the Kalinga War, coincides with the borders of modern-day Odisha. The modern boundaries of Odisha were demarcated by the British Indian government when Orissa Province was established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bhubaneswar
Bhubaneswar (; ) is the capital and largest city of the Indian state of Odisha. The region, especially the old town, was historically often depicted as ''Ekamra Kshetra'' (area (''kshetra'') adorned with mango trees (''ekamra'')). Bhubaneswar is dubbed the "Temple City", a nickname earned because of the 700 temples which once stood there. In contemporary times, it has emerged as an education hub and an attractive business destination. Although the modern city of Bhubaneswar was formally established in 1948, the history of the areas in and around the present-day city can be traced to the 7th century BCE and earlier. It is a confluence of Hindu, Buddhist and Jain heritage and includes several Kalingan temples, many of them from 6th–13th century CE. With Puri and Konark it forms the 'Swarna Tribhuja' ("Golden Triangle"), one of Eastern India's most visited destinations. Ramesh Prasad Mohapatra, ''Archaeology in Orissa'', Vol I, Page 47, B. R.
