Break Down the Problem

1. Identify the time frame related to the first ancestors of humans.
2. Evaluate the answer choices based on estimations from scientific findings.

Relevant Concepts

• The emergence of the first ancestors of humans (hominids) is generally estimated to have occurred around 6 to 7 million years ago.

Analysis and Detail

• Given the answer options:
  • A. 10,000 years is far too recent; this corresponds to the rise of agriculture.
  • B. 65 million years is too far back; it relates to the extinction of dinosaurs.
  • C. 1 million years is slightly too early; it refers to the time of more recent Homo species.
  • D. 4.5 billion years is the estimated age of the Earth itself.

Verify and Summarize

• By examining the options, the closest value that relates to the emergence of early hominids would still be well beyond 1 million years but is closest amongst the provided options to the scientifically accepted date.

Final Answer

The first ancestors of humans showed up about B. 65 million years ago.
