An evolutionary landscape is a metaphor [1] or a construct used to think about and visualize the processes of evolution (e.g. natural selection and genetic drift) acting on a biological entity [2] (e.g. a gene, protein, population, or species). [3] This entity can be viewed as searching or moving through a search space.
Landscape genetics is the scientific discipline that combines population genetics and landscape ecology. It broadly encompasses any study that analyses plant or animal population genetic data in conjunction with data on the landscape features and matrix quality where the sampled population lives.
Waddington called the effect he had seen "genetic assimilation". His explanation was that it was caused by a process he called "canalization".He compared embryonic development to a ball rolling down a slope in what he called an epigenetic landscape, where each point on the landscape is a possible state of the organism (involving many variables).
A landscape evolution model is a physically-based numerical model that simulates changing terrain over the course of time. The change in, or evolution of, terrain, can be due to: glacial or fluvial erosion, sediment transport and deposition, regolith production, the slow movement of material on hillslopes, more intermittent events such as rockfalls, debris flows, landslides, and other surface ...
The idea of a fitness landscape is a metaphor to help explain flawed forms in evolution by natural selection, including exploits and glitches in animals like their reactions to supernormal stimuli. The idea of studying evolution by visualizing the distribution of fitness values as a kind of landscape was first introduced by Sewall Wright in ...
Within his definition, the physical environment retains a central significance, as the medium with and through which human cultures act. [9] His classic definition of a 'cultural landscape' reads as follows: [7] "The cultural landscape is fashioned from a natural landscape by a cultural group. Culture is the agent, the natural area is the ...
Twelve percent of parents worry that their child’s anger will cause problems, according to a new poll. Experts weigh in on tips to manage their frustrations.
A naturally emergent landscape form that eases communication between areas. [2] acme See summit. acre (ac) A unit of area traditionally defined as the area of a plot of land one chain (66 feet) by one furlong (660 feet), equivalent to 43,560 square feet (0.001563 sq mi; 4,047 m 2), or about 0.40 hectare. active volcano
