Question

To which genus and species do modern humans belong? What were some of the other human species and what happened to them?

a. Genus: Homo, Species: sapiens; Other species: Homo neanderthalensis, Homo erectus, Homo habilis; Extinct or assimilated
b. Genus: Australopithecus, Species: afarensis; Other species: Homo sapiens, Homo neanderthalensis; Still existing
c. Genus: Homo, Species: neanderthalensis; Other species: Homo sapiens, Homo erectus; Extinct due to natural disaster
d. Genus: Pan, Species: troglodytes; Other species: Homo sapiens, Homo erectus; Extinct due to climate change

Answer 1

Modern humans are classified under the genus Homo and species sapiens. Previous human species such as Homo neanderthalensis, Homo erectus, and Homo habilis have either gone extinct or their genes have been assimilated into modern humans.

Therefore, option A ) is correct.

Step-by-step explanation:

Modern humans belong to the genus Homo and the species sapiens. Other human species that once existed include Homo neanderthalensis, Homo erectus, and Homo habilis. These species have either gone extinct or were assimilated into the modern human gene pool through interbreeding. For instance, the Neanderthals coexisted with modern humans and interbred, as is evident in the DNA of non-African people today. Other species, like Homo erectus, simply went extinct over time due to a variety of reasons including environmental changes and competition with other species.
