Neoteny. Neoteny (/ niˈɒtəni /), [1][2][3][4] also called juvenilization, [5] is the delaying or slowing of the physiological, or somatic, development of an organism, typically an animal. Neoteny is found more in modern humans compared to other primates. [6] In progenesis or paedogenesis, sexual development is accelerated.
Neoteny is the retention of juvenile traits well into adulthood. In humans, this trend is greatly amplified, especially when compared to non-human primates. Neotenic features of the head include the globular skull; [1] thinness of skull bones; [2] the reduction of the brow ridge; [3] the large brain; [3] the flattened [3] and broadened face; [2 ...
Recruitment in behavioral ecology. In behavioral ecology and studies of animal communication, recruitment is the process by which individuals in a social group direct other individuals to do certain tasks. [ 2 ] This is often achieved through the use of recruitment pheromones that direct anywhere from one to several hundred individuals to ...
The term ontogeny has also been used in cell biology to describe the development of various cell types within an organism. [4] Ontogeny is a useful field of study in many disciplines, including developmental biology, cell biology, genetics, developmental psychology, developmental cognitive neuroscience, and developmental psychobiology.
Life history theory. Life history theory (LHT) is an analytical framework [1] designed to study the diversity of life history strategies used by different organisms throughout the world, as well as the causes and results of the variation in their life cycles. [2] It is a theory of biological evolution that seeks to explain aspects of organisms ...
Developmental biology is the study of the process by which animals and plants grow and develop. Developmental biology also encompasses the biology of regeneration , asexual reproduction , metamorphosis , and the growth and differentiation of stem cells in the adult organism.
Human growthand development. Development of the human body is the process of growth to maturity. The process begins with fertilization, where an egg released from the ovary of a female is penetrated by a sperm cell from a male. The resulting zygote develops through mitosis and cell differentiation, and the resulting embryo then implants in the ...
In evolutionary developmental biology, heterochrony is any genetically controlled difference in the timing, rate, or duration of a developmental process in an organism compared to its ancestors or other organisms. This leads to changes in the size, shape, characteristics and even presence of certain organs and features.
