I added the "MRS GREN" section to the Life article because a new user had created a new article of that title with no sources at all, and with the simple definition. Rather than leave such a poor article in place, I created a section at the Life article for this new article to redirect to.
The key to life history theory is that there are limited resources available, and focusing on only a few life history characteristics is necessary. Examples of some major life history characteristics include: Age at first reproductive event; Reproductive lifespan and ageing; Number and size of offspring
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
The sexual part of the life cycle commences when two hyphal structures mate. In the case of homothallic species, mating is enabled between hyphae of the same fungal clone , whereas in heterothallic species, the two hyphae must originate from fungal clones that differ genetically, i.e., those that are of a different mating type .
To remember the order of taxa in biology (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species, [Variety]): "Dear King Philip Came Over For Good Soup" is often cited as a non-vulgar method for teaching students to memorize the taxonomic classification of system.
Generational change drives the cycle of turnings and determines its periodicity. As each generation ages into the next life phase (and a new social role) society's mood and behavior fundamentally change, giving rise to a new turning. Therefore, a symbiotic relationship exists between historical events and generational personas. Historical ...
A pine cone will go through many cycles of opening and closing during its life span, even after seed dispersal is complete. [3] This process occurs with older cones while attached to branches and even after the older cones have fallen to the forest floor .
Glen Elder theorized the life course as based on five key principles: life-span development, human agency, historical time and geographic place, timing of decisions, and linked lives. As a concept, a life course is defined as "a sequence of socially defined events and roles that the individual enacts over time" (Giele and Elder 1998, p. 22).
