Raw foodies: Europe's earliest humans did not use fire December 14, 2016 Cluster of starch granules in microfossils extracted from dental calculus. 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 w...

And for the most part, they do a pretty darn good job of it. Slap your SLR into AUTO mode and more often than not you’ll get images that are sharp with decent exposure. 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.

Here are five of the most essential camera settings, what they mean, and how they impact the photograph.
