Quizplus · Accepted Answer

The trellis or thicket provides the best metaphor for the multiregional metapopulation model of human evolution. This model suggests that different populations of early humans in various regions of the world interbred and exchanged genes over time, creating a branching network of interconnected populations that can be compared to a trellis or thicket. Just like the branches of a trellis or thicket connect and intertwine with each other, the populations of early humans were connected by gene flow, which allowed for the spread and exchange of genetic traits across regions.
