Social (and the resulting legal) attitudes toward the appropriate age of consent have drifted upwards in modern times. For example,ages from 10 to 13 were typically acceptable in western countries during the mid-19th century so many people globally married at the age of puberty even in North America
This is because early procreation was a necessity for human survival. Lifespan ranged from 20 to 30 years,due to high death rates. Even until the 18th century,8 children were still needed by each fertile wife just to maintain the population.
Also, sexual attraction accompanies puberty, which genetically ranges from ages 7 to 13 in women. So, whether one believes this instinct resulted from evolution, or part of God's plan, procreation after puberty in history is natural and acceptable.

• According to the Journal of Psychology & Human Sexuality, the "age of consent throughout history...usually coincided with the age of puberty" with "the absolute minimum at seven". Both that Journal and Encyclopedia Britannica state that age of consent laws were passed from Roman law to the Church to English Common Law, which states: "between 7 years and puberty there could be consent but not consummation" until puberty, with no parental consent required from the age of 12. This was confirmed in 1877 by the US Supreme Court. Even today, 6 states and the District of Columbia allow this Common Law marriage, and such marriages are then constitutionally recognized in all 50 states.
• Marriage as early as age 7, which was considered the "age of reason", or directly after puberty was the norm for the vast majority of all human society even until the 19th century.
