The gap begins in Yaviza, Panama and ends in Turbo, Colombia, and is 106 km (66 miles) long. Roadbuilding through this area is expensive and the environmental cost is high. Political consensus in favor of road construction has not emerged. Consequently, there is no road connection through the Darién Gap connecting North America with South America and it is the missing link of the Pan-American Highway.

Virtually all male U.S. citizens and male immigrant non-citizens between the ages of 18 and 25 are required by law to have registered within 30 days of their 18th birthdays and must notify Selective Service within ten days of any changes to any of the information they provided on their registration cards, like a change of address. A 2010 GAO report estimated the registration rate at 92% with the names and addresses of over 16.2 million men on file. However, the only audit of the addresses of registrants on file with the Selective Service System, in 1982, found that 20--40% of the addresses on file with the Selective Service System for registrants in the age groups that would be drafted first were already outdated, and up to 75% for those registrants in their last year of potential eligibility to be drafted would be invalid.

The term superfecundation is derived from fecund, meaning the ability to produce offspring. Heteropaternal superfecundation refers to the fertilization of two separate ova by two different fathers. Homopaternal superfecundation refers to the fertilization of two separate ova from the same father, leading to fraternal twins. While heteropaternal superfecundation is referred to as a form of atypical twinning, genetically, the twins are half siblings. Superfecundation, while rare, can occur through either separate occurrences of sexual intercourse or through artificial insemination.
