Final answer:
African slavery in North America experienced changes over the first century, including the shift towards permanence and the separation of families due to the trans-Atlantic slave trade.
Step-by-step explanation:
African slavery in North America underwent significant changes over the course of the first century. Initially, slavery existed alongside indentured servitude as the primary mode of labor in the South, particularly on tobacco and rice plantations. However, as the demand for labor grew, slavery became a permanent institution and children born to enslaved people also became enslaved, changing the nature of the institution in the New World. Additionally, the trans-Atlantic slave trade heavily impacted the lives of African slaves, subjecting them to inhumane conditions during the Middle Passage and separating families.
