Transcribed Image Text:The image presents a phylogenetic tree showcasing the evolutionary relationships among different hominin species. This tree traces the lineage from earlier hominins to various Homo species. The diagram can be described as follows:
1. **Earlier Hominins**: The tree begins with an ancestral group labeled as "earlier hominins." From this point, the tree splits into separate branches representing different species of the genus Homo.
2. **H. erectus**: One of the earliest branches leads to Homo erectus, an extinct species known for its significant role in early human migration out of Africa.
3. **H. floresiensis**: Another branch diverges to Homo floresiensis, often referred to as the "Hobbit" due to its smaller stature, discovered on the island of Flores in Indonesia.
4. **H. neanderthalensis**: This branch represents Homo neanderthalensis, commonly known as Neanderthals, who were prevalent in Europe and parts of Asia.
5. **H. heidelbergensis**: A close relative to both Neanderthals and modern humans, this branch is designated as Homo heidelbergensis.
6. **H. sapiens**: The final branch leads to Homo sapiens, modern humans, highlighting the culmination of evolutionary development in this tree diagram.
This phylogenetic tree provides an overview of how various Homo species are interconnected, emphasizing evolutionary divergence and adaptation over time.
