Credit: Karen Hardy Studying dental plaque from a 1.2 million year old hominin (early human species), recovered by the Atapuerca Research Team in 2007 in Sima del Elefante in northern Spain, archaeologists extracted microfossils to find the earliest direct evidence of food eaten by early humans. These microfossils included traces of raw animal tissue, uncooked starch granules indicating consumption of grasses, pollen grains from a species of pine, insect fragments and a possible fragment of a toothpick. All detected fibres were uncharred, and there was also no  evidence  showing inhalation of microcharcoal - normally a clear indicator of proximity to  fire . The timing of the earliest use of fire for cooking is hotly contested, with some researchers arguing habitual use started around 1.8 million years ago while other

If you are just looking to document your world, then go for it, snap away. The drawback is that images taken in AUTO tend to look similar to one another, with a uniform depth of field and exposure. If you want to move beyond the automatic camera settings, you need to understand your camera, how to use it, and most importantly, what impact changing those settings will have on your final image. Here are five of the most essential camera settings, what they mean, and how they impact the photograph.
