The theory was developed in the 1950s [4] and is used to answer questions about topics such as organism size, age of maturation, number of offspring, life span, and many others. [5] In order to study these topics, life history strategies must be identified, and then models are constructed to study their effects.
A person's livelihood (derived from life-lode, "way of life"; cf. OG lib-leit) [1] refers to their "means of securing the basic necessities (food, water, shelter and clothing) of life". Livelihood is defined as a set of activities essential to everyday life that are conducted over one's life span.

Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
The human pelvis exhibits greater sexual dimorphism than other bones, specifically in the size and shape of the pelvic cavity, ilia, greater sciatic notches, and the sub-pubic angle.

The finding that "Mitochondrial Eve" was relatively recent and African seemed to give the upper hand to the proponents of the Out of Africa hypothesis.But in 2002, Alan Templeton published a genetic analysis involving other loci in the genome as well, and this showed that some variants that are present in modern populations existed already in Asia hundreds of thousands of years ago.

A post-modern interpretation of the body theory emerged for the purpose of overturning the universal conceptions of the body. This view, which is called "new-body theory", emphasizes the relationship between the body and the self. [20] It produced the theories that explain the importance of the body in the contemporary social life.
