Draw a phylogeny of major populations of modern humans that would reject the out-of-Africa hypothesis.

Verified step by step guidance

1. Analyze the provided phylogenetic tree.
2. Identify the major populations of modern humans and their ancestors.
3. Note the branching points and timelines of each species.
4. Construct a phylogeny that shows multiple origins of modern humans, rejecting the out-of-Africa hypothesis.
5. Ensure the new phylogeny includes interbreeding and parallel evolution among different Homo species.

Key Concepts

Out-of-Africa Hypothesis

The Out-of-Africa hypothesis posits that modern humans (Homo sapiens) originated in Africa and migrated to other parts of the world, replacing local populations of archaic humans. This theory is supported by genetic and fossil evidence indicating a single origin of modern humans. Understanding this hypothesis is crucial for analyzing alternative theories of human evolution, including those that suggest multiple origins or interbreeding with other hominin species.

Phylogenetic Tree

A phylogenetic tree is a diagram that represents evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics. In the context of human evolution, constructing a phylogenetic tree helps visualize the lineage and divergence of different hominin species, including Homo habilis, Homo erectus, and others, which is essential for evaluating the validity of the Out-of-Africa hypothesis.

Hominin Diversity

Hominin diversity refers to the variety of species within the human lineage, including both extinct and extant species. This concept encompasses the evolutionary relationships and interactions among species such as Homo sapiens, Homo neanderthalensis, and Homo heidelbergensis. Recognizing this diversity is vital for understanding the complexity of human evolution and the potential for multiple origins or migrations that could challenge the Out-of-Africa hypothesis.
