Evolution of nakedness in Homo sapiens
A number of hypotheses have been proposed to account for Homo sapiens L. sapiens lacking in functionally effective thermally insulating fur, and these are presented in the light of current empirical evidence and discussion.
Parasitic Lice Help to Fill in the Gaps of Early Hominid History
The biology of the human pubic louse is examined in detail, which was transferred from a gorilla ancestor to a human ancestor about 3–4 million years ago, providing evidence of when humans lost their body hair and what habitats these early humans were using.
Ticks, Hair Loss, and Non-Clinging Babies: A Novel Tick-Based Hypothesis for the Evolutionary Divergence of Humans and Chimpanzees
A novel tick-based evolutionary hypothesis is proposed wherein forest fragmentation in hominin paleoenvironments created conditions that were favourable for tick proliferation, selecting for hair loss in hom inins and grooming behaviour in chimpanzees as divergent anti-tick strategies.
Avoidance of overheating and selection for both hair loss and bipedality in hominins
The model suggests that only when hair loss and sweating ability reach near-modern human levels could hominins have been active in the heat of the day in hot, open environments.
Human fine body hair enhances ectoparasite detection
The results show that fine body hair enhances the detection of ectoparasites through the combined effects of increasing the parasite's search time and enhancing its detection.

The results suggest that a preference for shaved genitalia may be explained by the superficial resemblance of pubic hair with chest hair, which is less developed as in the authors' evolutionary past, perhaps due to the benefits associated with ectoparasite avoidance.
What Makes Spiders Frightening and Disgusting to People?
The quality of human-animal interactions may crucially influence conservation efforts. Unfortunately, and despite their important roles in the functioning of the ecosystem, some animals are
Is plasticity in mating preferences adapted to perceived exposure to pathogens?
The results suggest that female perception of male trunk hair is not associated with a risk of contamination, which questions the salience of the ectoparasite avoidance hypothesis in explaining the loss of body hair in humans.
Is a Woman’s Preference for Chest Hair in Men Influenced by Parasite Threat?
Overall preference for man chest hair was low, but there were no significant associations between perceived vulnerability to diseases or disgust sensitivity and preference of men who have had experimentally removed chest hair.
Recent evidence suggests that several behavioural and emotional traits in humans evolved as a response to selective pressure caused by parasites, including disgust sensitivity and pathogen threat.


The Descent of Man, and Selection in Relation to Sex
I.IF Mr. Darwin had closed his rich series of contributions to Science by the publication of the “Origin of Species,“he would have made an epoch in Natural History like that which Socrates made in
The Scars of Evolution
When Elaine Morgan wrote The Descent of Woman in 1972, it sent shock waves around the world, and is now widely regarded as a key work on human evolution, and essential to any discussion of women's

This book discusses Recapitulation and Substantive Issues in Experimental Embryology: The New Preformationism, and the Importance of Heterochronic Change: Selected Cases.
Human Biology
In this plenary session each speaker highlights a different human biological feature, the ways in which it is known to vary, and how certain versions of it are understood to be normal, illustrating what is known about its statistical distribution, exposing normative meanings, and identifying the scientific foundations for them.
