OntogenyOntogeny (also ontogenesis) is the origination and development of an organism (both physical and psychological, e.g., moral development), usually from the time of fertilization of the egg to adult. The term can also be used to refer to the study of the entirety of an organism's lifespan. Ontogeny is the developmental history of an organism within its own lifetime, as distinct from phylogeny, which refers to the evolutionary history of a species.
Evolutionary developmental biologyHomologousHox genes in such different animals as insects and vertebrates control embryonic development and hence the form of adult bodies. These genes have been highly conserved through hundreds of millions of years of evolution.Evolutionary developmental biology, informally known as evo-devo, is a field of biological research that compares the developmental processes of different organisms to infer how developmental processes evolved.
Carl Friedrich KielmeyerCarl Friedrich Kielmeyer (22 October 1765 – 14 August 1844) was a German biologist and naturalist born in Bebenhausen, today part of the city of Tübingen. He was a pioneer of Naturphilosophie, helped to establish organic chemistry (Pflanzenchemie) as a field, and developed an early version of recapitulation theory through the observation of animal embryos.
EmbryoAn embryo ( ) is the initial stage of development for a multicellular organism. In organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization of the female egg cell by the male sperm cell. The resulting fusion of these two cells produces a single-celled zygote that undergoes many cell divisions that produce cells known as blastomeres.
LamarckismLamarckism, also known as Lamarckian inheritance or neo-Lamarckism, is the notion that an organism can pass on to its offspring physical characteristics that the parent organism acquired through use or disuse during its lifetime. It is also called the inheritance of acquired characteristics or more recently soft inheritance.
Étienne SerresAntoine Étienne Renaud Augustin Serres (12 September 1786, Clairac – 22 January 1868, Paris) was a French medical doctor and embryologist. He has been considered a pioneer of neurology. He was among the first to formulate the recapitulation theory. Life and workÉtienne Serres was the son of physician Jean Jacques Serres, "maître chirurgien" at Clairac and Marie Roussel.
BiologyBiology is the scientific study of life and living organisms. It is a broad natural science that encompasses a wide range of fields and unifying principles that explain the structure, function, growth, origin, evolution, and distribution of life.Cognitive developmentCognitive development is a field of study in neuroscience and psychology focusing on a child's development in terms of information processing, conceptual resources, perceptual skill, language learning, and other aspects of the developed adult brain and cognitive psychology.
Johann Friedrich MeckelJohann Friedrich Meckel (17 October 1781 – 31 October 1833), often referred to as Johann Friedrich Meckel, the Younger, was a German anatomist born in Halle. He worked as a professor of anatomy, pathology and zoology at the University of Halle, Germany. Life and researchIn 1802, he received his medicaldoctorate from the University of Halle, defending his doctoral thesis De cordis conditionibus abnormibus on 8 April 1802.
Music criticismThe Oxford Companion to Music defines music criticism as "the intellectual activity of formulating judgments on the value and degree of excellence of individual works of music, or whole groups or genres". In this sense, it is a branch of musical aesthetics. With the concurrent expansion of interest in music and information media since the turn of the 20th century, the term has come to acquire the conventional meaning of journalistic reporting on musical performances.
Phylogenetic treeA phylogenetic tree or phylogeny is a graphical representation which shows the evolutionary history between a set of species or taxa during a specific time. In other words, it is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics.ontogeny recapitulates phylogenyRelated word or term.*As an Amazon Associate I earn from qualifying purchases.
