Question

Put these names of our Hominin ancestors in order:

1. Sahelanthropus tchadensis
2. Ardipithecus ramidus
3. Australopithicus afarensis
4. Homo habilis
5. Homo erectus
6. Homo sapiens neanderthalensiss

Answer 1

The chronological order of hominin ancestors starts with Sahelanthropus tchadensis and continues with Ardipithecus ramidus, Australopithecus afarensis, Homo habilis, Homo erectus, and ends with Homo sapiens neanderthalensis, reflecting an evolution towards modern human traits.

Step-by-step explanation:

Hominin Ancestors Chronological Order

Understanding the timeline of hominin evolution is central to the study of human ancestry. The order of our hominin ancestors, based on fossil evidence and evolutionary theory, begins with the earliest known species and progresses to our own. Here are their names in chronological order of when they are generally believed to have existed:

1. Sahelanthropus tchadensis - Approximately 7 million years ago.
2. Ardipithecus ramidus - Around 4.4 million years ago.
3. Australopithecus afarensis - Flourished roughly between 3.9 and 3 million years ago.
4. Homo habilis - First appeared between 2.8 and 1.5 million years ago.
5. Homo erectus - Emerged about 1.9 million years ago and lasted until around 200,000 years ago.
6. Homo sapiens neanderthalensis (Neanderthals) - Existed approximately 400,000 to 40,000 years ago.

These hominin ancestors are crucial to our own history, showcasing a progression of evolutionary traits such as increased bipedalism, brain size, and tool-use that paved the way for modern humans.
