Homo sapiens L. is the only existing primate species lacking in functionally effective thermally insulating fur. As all other primates have considerable hair covering, it has always been accepted that our ancestors must once have had a respectable amount of body hair. Unfortunately, fossils cannot help us when it comes to differences in skin and hair. Recent DNA analysis, however, has given us some idea of when and where the great denudation took place. A number of hypotheses have been proposed… 
Fur or Fire: Was the use of fire the initial selection pressure for fur loss in ancestral hominins?
TLDR
This paper proposes a new hypothesis; that Homo sapiens ancestors use of fire created the initial selection pressure leading to fur loss in humans.
Parasitic Lice Help to Fill in the Gaps of Early Hominid History
TLDR
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
TLDR
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.
Lucy’s pelt: when we became hairless and how we managed to survive
  • A. Rebora
  • Biology
    International journal of dermatology
  • 2010
TLDR
The main problem is not why the authors became relatively hairless, but when such mutation occurred and how it was implausibly favored permitting humans not only to survive, but also to crowd out all other mammals.

Ecology of a widespread large omnivore, Homo sapiens, and its impacts on ecosystem processes
TLDR
The ecology of Homo sapiens is put in the context of comparative interspecific ecological roles and impacts, focusing on the large omnivore guild, as well as comparative intraspecific variation,ocusing on hunter‐gatherers.
Avoidance of overheating and selection for both hair loss and bipedality in hominins
TLDR
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.

Is plasticity in mating preferences adapted to perceived exposure to pathogens?
TLDR
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.
Body Size , Biology and Encephalization Quotient of Palaeoloxodon ex gr . P . falconeri from Spinagallo Cave ( Hyblean plateau , Sicily )
During the period of 1958 and 1960, the richest sample of Palaeoloxodon ex gr. P. falconeri (104 individuals) was recovered from Spinagallo cave (Syracuse, Hyblean Plateau, SE Sicily). Subsequently,

Allometry of primate hair density and the evolution of human hairlessness.
TLDR
It is proposed that, lacking a reflective coat of hair, the exploitation of eccrine sweating emerged as the primary mechanism for adaptation to the increased heat leads of man's new environment and permitted further reduction of the remnant coat to its present vestigial condition.

New partial skeleton of Homo habilis from Olduvai Gorge, Tanzania
TLDR
The craniodental anatomy indicates attribution to Homo habilis, but its postcranial anatomy, including small body size and relatively long arms, is strikingly similar to that of some early Australopithecus individuals.

TLDR
I must confess that I am not convinced of the action of sexual selection in producing the colours of insects, but it cannot be denied that these facts are strikingly corroborative of Mr. Darwin's views.

TLDR
Although it is true that most text-books of genetics open with a chapter on biometry, closer inspection will reveal that this has little connexion with the body of the work, and that more often than not it is merely belated homage to a once fashionable study.
