Final answer:
The correct way to present a species name is 'Homo erectus' with the genus name capitalized and the whole name italicized, following scientific conventions for binomial nomenclature.
Step-by-step explanation:
The correct presentation of a species name, according to the binomial nomenclature system, is Homo erectus where the genus name Homo is capitalized and the species name erectus is not, and the entire name is italicized. This follows the standardized format used in scientific contexts for naming species.
Homo erectus was an early species in the genus Homo that evolved around 1.9 million years ago. This species showed several traits that were more similar to modern humans compared to earlier hominins and is recognized for its widespread migration out of Africa to Eurasia. The discussion around whether Homo ergaster and Homo erectus are distinct species or the same reflects the complexity of human evolutionary history.
