Science Archaeology World's oldest-known rock art found in Indonesian cave The claw-like drawing of a human hand is roughly 67,800-years-old. Breakthroughs, discoveries, and DIY tips sent six days a week. A drawing of a claw-like hand on the wall of a cave in Sulawesi, Indonesia is now the oldest known rock art in the world. The roughly 67,800-year-old art exceeds the previous record holder in the same region of Southeast Asia by 15,000 years or more. The drawing is detailed in a study published today in the journal, and helps fill in the archaeological timeline of how and when Australia was first settled.

Music and dance are so deeply embedded in the human experience that we almost take them for granted. They're distinct from one another, but intimately related: Music -- arrangements of sound over time -- causes us to move our bodies in space. Without knowing it, we track pulse, tempo and rhythm, and we move in response. But only recently have scientists developed the tools, and the inclination, to quantitatively study the human response to music in its many forms. It's a research program that relies on a wide array of approaches, employing techniques from the study of perception and cognition to those of neurobiology and neuroimaging, with additional insights from psychophysics, evolutionary psychology and animal studies.

A collection of 5,000-year-old cave paintings depicting various figures and symbols has been discovered in Spain. The drawings were discovered in the rocky area of San Juan, near the town of Albuquerque in the province of Badajoz in western Spain. They are around 4 inches in length and include some anthropomorphic figures, as well as an arrow and other symbols, according to Spanish daily newspaper La Vanguardia. The doodlings were discovered by Agustín Palomo, an historic researcher who lives locally to the caves, while he was looking for a type of tomb known as a Dolmen. Mr Palomo immediately recognised their significance, given their location not far from two other well-known sets of cave drawings - 'Risco de San Blas', of the Sierra de la Carava and those of Azagala - the latter of which were only discovered around 20 years ago.
