Question

a. America
b. Africa
c. Asia
d. Europe

Answer 1

The period known as "middle Homo", which includes species Homo ergaster, Homo erectus, and Homo heidelbergensis, began in Africa about 1.9 million years ago with Homo erectus believed to be one of the first to migrate out of Africa.

Step-by-step explanation:

The period of "middle Homo", which includes species such as Homo ergaster, Homo erectus, and Homo heidelbergensis, is believed to have begun on the continent of Africa around 1.9 million years ago. Homo erectus, an early species in the genus Homo, first evolved in East Africa, and from there migrated to Eurasia before going extinct about 800,000 years ago. It is likely that Homo ergaster evolved in Africa as well, although there is some debate regarding whether Homo ergaster and Homo erectus are the same species or distinct due to their geographical distribution and minimal anatomical differences. Homo heidelbergensis, a transitional species in the genus Homo, probably evolved from Homo erectus and may have given rise to both Homo neanderthalensis and early Homo sapiens.
