Mammals have two kinds of sweat glands, apocrine and eccrine, which provide for thermal cooling. In this paper we describe the distribution and characteristics of these glands in selected mammals, especially primates, and reject the suggested development of the eccrine gland from the apocrine gland during the Tertiary geological period. The evidence strongly suggests that the two glands, depending on the presence or absence of fur, have equal and similar functions among mammals; apocrine glands…

Human evolution has been characterized by a marked decrease in body hair and an increase in the importance of pigment in the naked epidermis as a shield against the harmful effects of solar
Comparative evidence for the independent evolution of hair and sweat gland traits in primates
This work answers longstanding questions about the traits that make human skin unique and substantiates a model in which the evolution of expanded eccrine gland density was exclusive to the human lineage.
The evolution of eccrine sweat glands in human and nonhuman primates.
A genetic basis of variation in eccrine sweat gland and hair follicle density
This work uncovers a previously unidentified biological factor that specifically promotes the development of eccrine glands when these organs are interspersed with hair follicles, and identifies a pathway that could have contributed to the evolution of the unique features of human skin.
Neural control of sweat secretion: a review
Human sweat glands can be classified into two types: eccrine and apocrine glands, which are directly involved in thermoregulation and metabolism and is regulated by both the central nervous system and autonomic nervous system.
Abolished InsP3R2 function inhibits sweat secretion in both humans and mice.
5 members of a consanguineous family with generalized, isolated anhidrosis, but morphologically normal eccrine sweat glands are reported and data indicate that loss of InsP3R2-mediated Ca2+ release causes isolatedAnhidrosis in humans and suggest that specific InsP 3R inhibitors have the potential to reduce sweat production in hyperhidrosis.
Effects of denervation on palmar sweating in the rhesus monkey (Macaca mulatta)
The effects of denervation on the response of eccrine sweat glands to exogenous methacholine and the denervated sweat glands remained histologically normal throughout the 5 weeks of observation are observed.
The Multiple Facets of Dermcidin in Cell Survival and Host Defense
This review summarizes the evidence gathered until now concerning the expression of dermcidin and the functional relevance of derMCidin-derived peptides and states that peptides processed from the dermcIDin precursor protein exhibit a range of other biological functions in neuronal and cancer cells.


Allometry of primate hair density and the evolution of human hairlessness.
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.
In vivo and in vitro characteristics of eccrine sweating in patas and rhesus monkeys.
The patas monkey is an excellent model for studying the physiology of sweating in humans and its sweating rates, measured by resistance hygrometry during exercise in a hot (40 degrees C) environment, are indicated.
Functional and morphological changes in the eccrine sweat gland with heat acclimation.
It is concluded that heat acclimation increases the size of eccrine sweat glands and that these larger glands produce more sweating and are also more efficient because they produce more sweat per unit length of secretory coil.
Primate Evolution and Human Origins
Primate Evolution and Human Origins compiles, for the first time, the major ideas and publications that have shaped our current view of the evolutionary biology of the primates and the origin of the
Primate Adaptation and Evolution
This new edition brings this coverage up to date with the latest fossil finds and most current research, and retains its grounding in the extant primate groups as the best way to understand the fossil trail and the evolution of these modern forms.
Some Effects of High Air Temperatures and Muscular Exertion upon Colliers.
This paper deals with the work undertaken by the author while he was Tyndall Research Student of the Royal Society. The investigations fall under the following four distinct headings:— 1. The Food

The importance of free convection in a sample of fleece with a diameter of 20 cm was demonstrated by showing that the thermal conductivity was independent of windspeed but increased with the temperature difference between the skin and the air or (Ts — Ta).
Why do Bedouins wear black robes in hot deserts?
Survival in hot deserts has always posed a problem for man; Moses had to solve it in order to lead the children of Israel through the wilderness of the Sinai—a formidable hot desert. It seems likely
