All primates except human beings have thick coats of body hair. This suggests the primate ancestors of human beings likewise had such body hair and that, for some evolutionary reason, lost their body hair. Various theories have been put forward but none is fully adequate. This article presents the “naked love theory.” This theory locates the origin of human hairlessness in the ancestral mother-infant relationship. In this view, hairlessness is ultimately the adaptive consequence of bipedalism… 
The Evolution of Human Sociability: Desires, Fears, Sex and Society
TLDR
Professor Vannelli argues that human nature can be conceptualized as species-typical desires and fears, derived from sexual selection during human evolution, and that these can be treated as major motivators of human behaviour.
How scientists perceive the evolutionary origin of human traits: Results of a survey study
TLDR
The most popular hypotheses were based on inherent drivers; that is, they assumed the evolution of a trait to have been triggered by the prior emergence of another human‐specific behavioral or morphological trait, but opinions differed as to which of the traits came first.
Thermoregulation in mice, rats and humans: An insight into the evolution of human hairlessness
TLDR
The rat's loss of tail hair and human's Loss of its body hair are responses to these conflicting thermoregulation needs as these animals evolved to larger size over time.

TLDR
The hypothesis that humans evolved hairlessness to reduce parasite loads, especially ectoparasites that may carry disease is proposed and explains features of human hairlessness—such as the marked sex difference in body hair, and its retention in the pubic regions—that are not explained by other theories.

Influence of Naked Body Contact Between Mother and Newborn on Effective Breastfeeding
TLDR
The study explored breastfeeding initiation practices at the time of birth and examined relationships between duration of naked body contact and a range of breastfeeding and maternal outcomes.

TLDR
Olfactory cues signaling women’s levels of reproductive fertility were associated with specific endocrinological responses in men—responses that have been linked to sexual behavior and the initiation of romantic courtship.
