    Clovis phase spear points used in present-day Alberta.

    Clovis phase spear points represent the oldest hunting technology in Alberta, and indeed all of North America. These fluted, jagged stone points would be attached to a bone or wooden shaft and used to hunt enormous prey such as mammoths and mastodons.

    Atlatl (spear-thrower) technology emerges in present-day Alberta.

    Atlatls were used by early hunter’s to increase the velocity of their projectile weapons. Spears or darts thrown with an atlatl could deliver devastating wounds to an animal, allowing the hunter to kill the animal from a safe distance.

    Bow and arrow technology reaches present-day Alberta.

    Bow and arrow technology in North America appears to have developed first in the Arctic before spreading south throughout the continent. The bow and arrow was ideally suited for use in the wide open spaces of the Great Plains, and was widely adopted across the region.

    The ‘Horse Revolution’ begins in present-day Alberta.

    Horses were brought to North America by Spanish colonists in the sixteenth century. From the Spanish colony of New Mexico, horses spread across North America, reaching present-day Alberta in the 1730s. The adoption of the horse had a significant impact on the hunting/transportation patterns of Plains First Nations peoples.

    Rocky Mountains National Park is established by the Canadian government.

    One of the main attractions of the new park was the site’s natural hot springs. The luxurious Banff Springs Hotel, built by the Canadian Pacific Railway in 1888, pumped water from the hot springs into its swimming pools and treatment rooms. Tourists flocked to the site to take advantage of the water’s supposed therapeutic healing powers.

    The Calgary Power Company is formed.

    The founder of the company, Max Aitken, was initially drawn to the region by its vast hydroelectricity potential. The company would develop into Canada’s largest investor-owned utility. In 1981, the company changed its name to TransAlta Utilities Corporation, in order to better reflect its provincial reach.

    Voters of Alberta narrowly reject proposal for public ownership of electricity utilities.

    The 1948 provincial election included a plebiscite concerning ownership of electricity utilities in Alberta. Rural areas largely voted in favour of public ownership, while urban voters (particularly in southern Alberta) supported a continuation of private ownership. In the end, the vote was extremely close, with public ownership defeated by a mere 151 votes.

Animal Power in Prehistoric Times

The taming of wild animals to live and work with people dramatically increased the amount of energy available to humans. As many societies transitioned from hunting and gathering to settlement and agriculture, a wide variety of animals were domesticated for human use. Goats and sheep were tamed and raised for food, while oxen, donkeys and horses were used as draft animals. The results, in short, were revolutionary.

The domestication of animals was a process rather than an event, and occurred slowly over a period of thousands of years in different regions of the world. Archaeological evidence suggests that the earliest domestication of animals occurred in western Asia around 8,000 BCE as humans increasingly turned to farming for their food supply. Goats and sheep were tamed and raised for their meat, milk and hides (in the case of sheep, wool). By 6,000 BCE, humans had started to tame the wild ox, or aurochs, an animal that lived throughout much of Asia and Europe. Domesticated cattle proved to be much more versatile than goats or sheep: in addition to providing food, milk, and hides, cattle could be harnessed to till fields using early versions of the plow. The muscle power of cattle, and later donkeys and horses, dramatically increased the efficiency of farming, allowing for greater crop yields that supported larger populations and ultimately contributed to the rise of cities.

In addition to having economic and social impacts, the domestication of animals was a process that had profound social

consequences. The centrality of cattle, in particular, in the mythologies and religious beliefs of many early societies reveals the extent to which the importance of the animal was quickly embedded into their cultures. Prehistoric cave paintings in France and Spain, some as old as 30,000 BCE, include many scenes depicting aurochs, suggesting the animal was culturally significant long before it was domesticated. Cattle are sacred in the Hindu tradition and prominent in the religion’s ancient sacred texts. Archaeological excavations on the Greek island of Crete suggest the bull was central to the religious ceremonies of the ancient Minoan people; this was also reflected in Greek mythology, as the labyrinth on Crete was believed to be the home of the Minotaur, a monstrous creature that was half-man, half bull. Finally, the greatest epic in Celtic mythology, the “Cattle Raid of Cooley,” tells the story of a long and terrible war between two Irish kingdoms over possession of an awesome, magical beast, the great Brown Bull. Indeed, cattle were so important in Ireland, they were used as currency until the arrival of minted coins in the ninth century.

The domestication of animals represents one of the most important turning points in human history. The ability to harness the energy of animals to help in the production of food was a revolutionary development that had social, economic and cultural consequences that can be seen to this day.

Animal Power in Prehistoric Alberta

The domestication of animals in prehistoric Alberta followed a very different pattern than the one seen in Africa, Asia and Europe.

The “Horse Revolution”

In the early sixteenth century, Spanish invaders conquered and colonized much of present-day Central America.
