Final answer:
Turkana people, like many other ethnic groups, might have historical practices of exogamy, but it's also common for some members to marry within to maintain blood quantum. Policies are shifting to allow tribal membership by descent. In modern times, marrying outside one's group is increasingly accepted, particularly in urban areas.
Step-by-step explanation:
The question of whether Turkana people only marry outside of their clan is related to their cultural practices of marriage and exogamy. While traditional practices among various tribes and ethnic groups can differ, many communities have historically practiced exogamy, which refers to marriage outside one's core social unit. This practice can help to build alliances between different clans and groups. However, it's also not uncommon for some tribal members to marry within their own group to maintain a high percentage of blood quantum, as seen in other indigenous communities. In modern times, manyare reviewing and adjusting membership requirements, allowing individuals to claim membership by descent rather than strict blood quantum levels.
In many societies, exogamy is now more accepted, and with the eradication of miscegenation laws and a trend toward celebrating multi-ethnic identities, the stigma attached to marrying outside one's ethnic or racial group is decreasing. The trend of marrying outside one's clan or ethnic group is not just limited to traditional societies but is also seen more widespread in cosmopolitan urban areas where cultural diversity may lead to an increase in mixed marriages.
