Discoveries and Innovations contributing to Building Construction and Real Estate


70,000 years ago (Seven hundred past generations) approximately 10 to 15 thousand breeding humans walked the earth.    

Ten thousand people occupy approximately one tenth of the average football stadium of today and I have difficulty creating a family tree with more than three generations.



Today’s world population is said to be over seven billion with over 314 million in the United States.

The thought of these first humans building shelters or habitats inspired me to research the Internet (Google searches by “History of” and topic) for discoveries and innovations contributing to Building Construction and ultimately Real Estate.

Here are my findings:

The earth’s surface has approximately 196,939,900 square miles.  Oceans comprise approximately 70 per cent of the earth’s surface or approximately 137,857,930 square miles and the remaining land is 59,081,970 sq miles.

These first humans owned a lot of land.

Earth has been divided into five continents (Africa, America, Asia, Australia and Europe); but some say seven continents (Africa, Antarctica, Asia, Australia, Europe, North America and South America).   

Africa, Asia and Europe BC discoveries included the Hammer (Stones for striking wood and bone), Drill (pointed rock spun between hands) and Tongs (sticks for handling fires) were the first tools followed by the Shovel (Ox shoulder blades used to move soil and rock), Saw, Rope (from water reed fibers) and bronze nails.  The most significant America discoveries are AD via Europe. 

Here are a few of the most significant (in my opinion) contributions in chronological order by continent:

Africa 2.4 Mil to 400 BC
Asia 10000 to 1000 BC
Europe 6400 to 300 BC

Apparently no significant contributions associated with the advancement of building construction since 1975.

Comments welcome with any overlooked and/or additional contributions to the Building Construction and/or Real Estate Industries.

  1. Too many would-be real estate agents obsess over the licensing test, then fail in their first two years because they didn't develop a plan and follow it for success in becoming a real estate agent. They passed the test, but failed to understand the business, to develop a budget and a business plan, or to learn the ropes that aren't taught or covered in the test. These are not just tips, but tools to help you to go into the business with a plan in place to be successful. Learning about the pace of the business, the costs of doing business, and getting to the right prospects is critical.
