Jacob and Calvin agreed that even if no one watched their YouTube videos, they’d still be exploring the hundreds of local underground lava tubes and tree casts of southern Washington and Oregon, created by past eruptions from nearby volcanoes such as Mount Saint Helens. They both grew up hiking, and sometimes their family chose caves over waterfalls to visit along the way. Recalling the show's live debut for Twiggy, he said: "I've got a Max Wall wig, long hair and a caveman fur and fake rubber feet ... got these fake teeth and the audience just looked at me like I was completely mad. And it didn't get much better. By the end, they were looking at me as if 'when's this going to stop?'"

Neanderthal teeth also serve as a point of recognition in their anatomy. This is because Neanderthal teeth illustrate non-primitive accounts, and different frequencies when in comparison to modern humans. The research behind Neanderthal teeth morphology shows that it is a unique characteristic and evolutionary trait specifically only found within Neanderthals.

In 2021, the DIY guru created another viral sensation—the unorthodox Caveman Slippers, modelled after human feet. As frightening and grotesque as they are, the Caveman Slippers are perfectly in-line with Moosvi’s sense of humor and previous work.

In October 2018, scientists announced the 3-D virtual reconstruction, for the first time, of a Neanderthal rib cage, which may help researchers better understand how this ancient human species moved and breathed. [11] [12] Increasingly longer hours spent inside office buildings and homes, rather than visually stimulating landscapes like forests and other natural spaces, can also lead to sight problems, Lieberman said. But humans take this risk, and manage to get by fine with glasses.Trinkaus E, Holliday TW, Auerbach BM (March 2014). "Neandertal clavicle length".

But cavemen weren't watching their calories; they just didn't have access to the huge quantities of sugar available today. Modern technology allows humans to extract sugar from a wide range of sources — including sugar cane, maple trees, beehives and corn stalks — and ship that sugar around the world in huge quantities and at unprecedented speeds.Arthritis was common in the older Neanderthal population, specifically targeting areas of articulation such as the ankle (ShanidarIII), spine and hips (La Chapelle-aux-Saints 'Old Man'), arms ( La Quina 5, Krapina, Feldhofer) knees, fingers and toes. This is closely related to degenerative joint disease, which can range from normal, use-related degeneration to painful, debilitating restriction of movement and deformity and is seen in varying degree in the Shanidar skeletons (I–IV). The exhilaration of discovery, being somewhere that no one else has ever been, drives the cavers to keep pushing. This year, Bauman and the grotto plan to survey an additional 58,000ft, or about 10 miles, of caves. Froehle AW, Churchill SE (2009).

Long clavicles (however, Neanderthal clavicles are not relatively long if corrected for body weight and are proportionately similar to those of modern humans [19]) The librarian of the Oregon Grotto, which is a bit of a misnomer because it’s focused on southern Washington, is the official keeper of approximately 600 tightly protected cave maps that reveal the secret locations of every documented cave in the region. Because the maps can present a danger to inexperienced hikers and can seem inviting to vandals and litterers when they are made public, members of the grotto commit to keeping locations private.Smith TM, Toussaint M, Reid DJ, Olejniczak AJ, Hublin JJ (December 2007).

But Lieberman pointed out that myopia — also known as nearsightedness, when far-away objects look blurry — has increased substantially with the advent of writing and reading. This is because the eye muscles, which are not made for prolonged up-close vision, must strain to look at things close to the face, and eventually they stretch and elongate to the point that they no longer function properly.
