I wonder what the evolutionary purpose of a beard is, 
From an evolutionary viewpoint the beard is a part of the broader category of androgenic hair.

Fusiform face area
The fusiform face area - FFA ("meaning": spindular/spindle-shaped face area) is a part of the human visual system that is specialized for facial recognition. It is located in the Inferior temporal cortex (IT), in the fusiform gyrus (Brodmann area 37). The FFA is located in the ventral stream on the ventral surface of the temporal lobe on the lateral side of the fusiform gyrus. It is lateral to the parahippocampal place area. It displays some lateralization, usually being larger in the right hemisphere. The FFA was discovered and continues to be investigated in humans using positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) studies.
Beard
A beard is the collection of hair that grows on the chin and cheeks of humans and some animals. In humans, usually only pubescent or adult males are able to grow beards. From an evolutionary viewpoint the beard is a part of the broader category of androgenic hair. It is a vestigial trait from a time when humans had hair on their face and entire body like the hair on gorillas. The evolutionary loss of hair is pronounced in some populations such as indigenous Americans and some east Asian populations, who have less facial hair, whereas people of European or South Asian ancestry and the Ainu have more facial hair.
Evolutionary psychology
Evolutionary psychology is a theoretical approach in the social and natural sciences that examines psychological structure from a modern evolutionary perspective. It seeks to identify which human psychological traits are evolved adaptations – that is, the functional products of natural selection or sexual selection in human evolution. Adaptationist thinking about physiological mechanisms, such as the heart, lungs, and immune system, is common in evolutionary biology. Some evolutionary psychologists apply the same thinking to psychology, arguing that the modularity of mind is similar to that of the body and with different modular adaptations serving different functions.
McCreary County v. American Civil Liberties Union
McCreary County v. ACLU of Kentucky, , was a case argued before the Supreme Court of the United States on March 2, 2005. At issue was whether the Court should continue to inquire into the purpose behind a religious display and whether evaluation of the government's claim of secular purpose for the religious displays may take evolution into account under an Establishment Clause of the First Amendment analysis. In a suit brought by the American Civil Liberties Union of Kentucky, the United States Court of Appeals for the Sixth Circuit held that the displays—in this case, a Ten Commandments display at the McCreary County courthouse in Whitley City, Kentucky and a Ten Commandments display at the Pulaski County courthouse—were unconstitutional.
Supernormal Stimuli
Supernormal Stimuli: How Primal Urges Overran Their Evolutionary Purpose is a book by Deirdre Barrett published by W. W. Norton & Company in 2010. Barrett is a psychologist on the faculty of Harvard Medical School. The book argues that human instincts for food, sex, and territorial protection evolved for life on the savannah 10,000 years ago, not for today's densely populated technological world. Our instincts have not had time to adapt to the rapid changes of modern life. The book takes its title from Nikolaas Tinbergen's concept in animal ethology of the supernormal stimulus, the phenomena by which insects, birds, and fish in his experiments could be lured by a dummy object which exaggerated one or more characteristic of the natural stimulus object such as giant brilliant blue plaster eggs which birds preferred to sit on in preference to their own.
Alcohol dehydrogenase
Alcohol dehydrogenases (ADH) () are a group of dehydrogenase enzymes that occur in many organisms and facilitate the interconversion between alcohols and aldehydes or ketones with the reduction of nicotinamide adenine dinucleotide (NAD to NADH). In humans and many other animals, they serve to break down alcohols that otherwise are toxic, and they also participate in generation of useful aldehyde, ketone, or alcohol groups during biosynthesis of various metabolites. In yeast, plants, and many bacteria, some alcohol dehydrogenases catalyze the opposite reaction as part of fermentation to ensure a constant supply of NAD.
Chromoplast
Chromoplasts are plastids, heterogeneous organelles responsible for pigment synthesis and storage in specific photosynthetic eukaryotes. It is thought that like all other plastids including chloroplasts and leucoplasts they are descended from symbiotic prokaryotes. Chromoplasts are found in fruits, flowers, roots, and stressed and aging leaves, and are responsible for their distinctive colors. This is always associated with a massive increase in the accumulation of carotenoid pigments. The conversion of chloroplasts to chromoplasts in ripening is a classic example. They are generally found in mature tissues and are derived from preexisting mature plastids.

Most likely to keep the face warm, but i like having a beard because people don't mess with me when i have one.  A beard makes me look threatening.  That may also have some evolutionary purpose.
