The next stage involved interaction with burned landscapes and foraging in the wake of wildfires, as observed in various wild animals. Such a change may have occurred about 3 Mya, when the savanna expanded in East Africa due to cooler and drier climate. One was a change in habitat, from dense forest, where wildfires were common, to savanna (mixed grass/woodland) where wildfires were of higher intensity.

Use and control of fire was a gradual process proceeding through more than one stage.

4.1.5 Developments and expansion in early hominid societies.

Evidence of widespread control of fire by anatomically modern humans dates to approximately 125,000 years ago. Fire was used regularly and systematically by early modern humans to heat treat silcrete stone to increase its flake-ability for the purpose of toolmaking approximately 164,000 years ago at the South African site of Pinnacle Point. Flint blades burned in fires roughly 300,000 years ago were found near fossils of early but not entirely modern Homo sapiens in Morocco. Evidence for the "microscopic traces of wood ash" as controlled use of fire by Homo erectus, beginning roughly 1 million years ago, has wide scholarly support. Additionally, creating fire allowed human activity to continue into the dark and colder hours of the evening.Ĭlaims for the earliest definitive evidence of control of fire by a member of Homo range from 1.7 to 2.0 million years ago ( Mya). These cultural advances allowed human geographic dispersal, cultural innovations, and changes to diet and behavior. Fire provided a source of warmth and lighting, protection from predators (especially at night), a way to create more advanced hunting tools, and a method for cooking food. This of course is a mere sketch.The control of fire by early humans was a critical technology enabling the evolution of humans.

Wineries in Santa Barbara and San Luis Obispo Counties are making wonderful Syrahs, and the Sierra Foothill appellations are proving to be an experimental hotbed, with Italian and Spanish varietals employed to great effect. As for Pinot Noir, terrific examples can be found from AVA’s such as Anderson Valley, Carneros, Santa Lucia Highlands and Sta. The much larger and climatically varied Sonoma County also produces world class California Cabernet, along with wonderful examples of California Pinot Noir and Zinfandel.įine versions of Cabernet and Zinfandel hail from Paso Robles as well, which is also gaining fame with Rhone varietals like Syrah and Grenache. But California boasts a wealth of other impressive appellations. The state’s most famous red wine region, of course, is Napa Valley, where Cabernet Sauvignon reigns as king. This leads to well-developed fruit marked both by impressive ripeness and balancing acidity. While the state’s incredibly diverse geography, soils and microclimates allow for a wide array of styles, the key factor unifying California red wine is the abundance of sunshine and a long, consistent growing season. In addition, a number of California red wines are heralded as being among the most prestigious and sought-after wines in the world.

Red wine accounts for 56% of the total by volume, and red grapes 63% of total acres planted. California is a winemaking colossus by itself it is the fourth largest producer in the world.
