Human beings like to be warm and dry. It is built into all of us. To this end we have tried, from the age of the cave people, to ensure that we have a warm and well light living space. Whilst this may well mean just an open roaring fire in the beginning, human ingenuity in this field means we now have something amazing like Downlight Covers that help to retain heat in the home. What have we used to heat our home down through the years.
The people of the Paleolithic had discovered fire completely by accident. They understood how to make it and began to fell trees as wood seemed to be the best fuel. It is easy to imagine them all huddled around this source of heat. As they moved out of the caves and entered into the Mesolithic age they still needed to warm themselves. More trees were felled for fuel and also for field space to grow cereals and crops. From evidence found it seems that they favoured the open fire but began to find ways to vent the smoke.
By the Neolithic stage, roundhouses of Wattle and Daub with Willow roofs were starting to become the norm. They left a gap to vent the smoke but in many respects they all still came together to hunker down in front of the fire and make up the first tales to entertain themselves as the cave people did.
