Place the following important hominin fossils in chronological order, from oldest to most recent: Australopithecus afarensis, Homo habilis, Homo erectus, Homo neanderthalensis.
A
Homo habilis → Australopithecus afarensis → Homo erectus → Homo neanderthalensis
B
Australopithecus afarensis → Homo erectus → Homo habilis → Homo neanderthalensis
C
Australopithecus afarensis → Homo habilis → Homo erectus → Homo neanderthalensis
D
Homo erectus → Australopithecus afarensis → Homo habilis → Homo neanderthalensis
Verified step by step guidance1
Step 1: Understand the problem by identifying the task, which is to place the hominin fossils in chronological order based on their evolutionary timeline.
Step 2: Recall the general timeline of hominin evolution. Australopithecus afarensis is one of the earliest hominins, followed by Homo habilis, then Homo erectus, and finally Homo neanderthalensis.
Step 3: Compare the options provided in the problem. The correct sequence should align with the evolutionary timeline: Australopithecus afarensis → Homo habilis → Homo erectus → Homo neanderthalensis.
Step 4: Eliminate incorrect options by checking the order of fossils against the known timeline. For example, Homo erectus cannot precede Australopithecus afarensis as it evolved later.
Step 5: Confirm the correct answer by verifying that the sequence matches the evolutionary progression of hominins: Australopithecus afarensis → Homo habilis → Homo erectus → Homo neanderthalensis.
