Pre-Clovis migration along the American Pacific Coast

Arriving to the Americas between 10 and 12 thousand years ago, the Clovis "culture" was the largest human migratory wave to reach the American continent. Uniquely identified by their lithic tradition, these were not one particular ethnic group, but several, from which many present-day Native Americans are descended. However, we have evidence of previous migrations that delay the population of America till 30,000 years ago ±. Known collectively as the Pre-Clovis, it is hypothesized that they descended the American Pacific coast in ships while subsisting primarily on marine resources. These groups are the probable progenitors of several specific indigenous lineages and perhaps help explain the existence of isolated linguistic groups and the high admixture of archaic genetics, as well as that of other contemporary human groups in certain present-day indigenous populations.

Further more, migrations into and *out* of the continent would continue for centuries and millennia after the Clovis, which complicates the picture even more. Hopefully, future archaeological and genetic research will help us elucidate this increasingly complex and fascinating period of human movement.
