Theories of domestic catâs For decades, many theories have existed to explain the origin of cats. Traditionally, most scholars believed that all domestic cats had a common ancestor in ancient Egypt, where cats were domesticated around 3,600 years ago. Other researchers believed that domestic cats had more than one ancestor, the result of domestication occurring at different times and places, each resulting in a distinct ancestral breed 1.
Railroads usually consider a 100 ft. width of right of way centered about their main track centerline as the minimum on which they can effectively operate. Any encroachment within this limit, even if it is only for ditch cleanout or erosion control, is not welcomed by the railroad and therefore is to be avoided.
The average width of a car lane is 9 feet which is equivalent to  2.7 meters. However, this may vary in some cases like highways  which are 3.7 meters or 12 feet wide.t depends on what type of road or parking area the lane is in. I remember working for an Architect who did a lot of bank work, which have drive-thru lanes. The width of the lane at the outdoor teller station was either 7' or 8' wide, depending upon the preference of the owner.
