AposematismAposematism is the advertising by an animal to potential predators that it is not worth attacking or eating. This unprofitability may consist of any defenses which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These advertising signals may take the form of conspicuous coloration, sounds, odours, or other perceivable characteristics. Aposematic signals are beneficial for both predator and prey, since both avoid potential harm.
Signalling theoryWithin evolutionary biology, signalling theory is a body of theoretical work examining communication between individuals, both within species and across species. The central question is when organisms with conflicting interests, such as in sexual selection, should be expected to provide honest signals (no presumption being made of conscious intention) rather than cheating. Mathematical models describe how signalling can contribute to an evolutionarily stable strategy.
Uttar PradeshUttar Pradesh (ˌʊtər_prəˈdɛʃ; 'North Province') is a state in northern India. With over 241 million inhabitants, it is the most populated state in India as well as the most populous country subdivision in the world – more populous than all but four countries – accounting for 16.5% of the total population of India. It was established in 1950 after India had become a republic. It is a successor to the United Provinces, established in 1935 by renaming of the United Provinces of Agra and Oudh, in turn established in 1902 from the North-Western Provinces and the Oudh Province.
Structural colorationStructural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination with pigments. For example, peacock tail feathers are pigmented brown, but their microscopic structure makes them also reflect blue, turquoise, and green light, and they are often iridescent.
KeralaKerala (ˈkɛrələ ; ke:ɾɐɭɐm) is a state on the Malabar Coast of India. It was formed on 1 November 1956, following the passage of the States Reorganisation Act, by combining Malayalam-speaking regions of the erstwhile regions of Cochin, Malabar, South Canara, and Travancore. Spread over , Kerala is the 21st largest Indian state by area. It is bordered by Karnataka to the north and northeast, Tamil Nadu to the east and south, and the Lakshadweep Sea to the west.
SaraswatiSaraswati (सरस्वती, ) is the Hindu goddess of knowledge, music, art, speech, wisdom, and learning. She is one of the Tridevi, along with the goddesses Lakshmi and Parvati. The earliest known mention of Saraswati as a goddess is in the Rigveda. She has remained significant as a goddess from the Vedic period through the modern period of Hindu traditions. She is generally shown to have four arms, holding a book, a rosary, a water pot, and a musical instrument called the veena. Each of these items have a symbolic meaning in Hinduism.
Animal colorationAnimal colouration is the general appearance of an animal resulting from the reflection or emission of light from its surfaces. Some animals are brightly coloured, while others are hard to see. In some species, such as the peafowl, the male has strong patterns, conspicuous colours and is iridescent, while the female is far less visible. There are several separate reasons why animals have evolved colours. Camouflage enables an animal to remain hidden from view.
Ronald FisherSir Ronald Aylmer Fisher (17 February 1890 – 29 July 1962) was a British polymath who was active as a mathematician, statistician, biologist, geneticist, and academic. For his work in statistics, he has been described as "a genius who almost single-handedly created the foundations for modern statistical science" and "the single most important figure in 20th century statistics". In genetics, his work used mathematics to combine Mendelian genetics and natural selection; this contributed to the revival of Darwinism in the early 20th-century revision of the theory of evolution known as the modern synthesis.
KartikeyaKartikeya (Kārttikeya), also known as Skanda, Subrahmanya, Shanmukha (), Murugan (முருகன்), and is the Hindu god of war. He is the son of Parvati and Shiva, the brother of Ganesha and a god whose legends have many versions in Hinduism. Kartikeya has been an important deity in the Indian subcontinent since ancient times, worshipped as Mahasena and Kumara in North India and is predominantly worshipped in the state of Tamil Nadu and other parts of South India, Sri Lanka, Singapore, Malaysia and Mauritius by Tamils as Murugan.
RigvedaThe Rigveda or Rig Veda (ऋग्वेद , from "praise" and "knowledge") is an ancient Indian collection of Vedic Sanskrit hymns (sūktas). It is one of the four sacred canonical Hindu texts (śruti) known as the Vedas. Only one Shakha of the many survive today, namely the Śakalya Shakha. Much of the contents contained in the remaining Shakhas are now lost or are not available in the public forum. The Rigveda is the oldest known Vedic Sanskrit text. Its early layers are among the oldest extant texts in any Indo-European language.
