Homo sapiens have evolved in

Options

A. Paleocene
B. Pleistocene
C. Oligocene
D. Miocene

Answer

To determine when Homo sapiens evolved, we can follow these steps:

### Step 1: Understand the Options
The question provides four geological epochs: Paleocene, Pleistocene, Oligocene, and Neocene. We need to identify which of these is associated with the evolution of Homo sapiens.

### Step 2: Define the Epochs
- **Paleocene**: This epoch occurred from about 66 to 56 million years ago and is primarily known for the rise of mammals after the extinction of dinosaurs.
- **Oligocene**: This epoch lasted from about 34 to 23 million years ago and saw the diversification of mammals and birds.
- **Pleistocene**: This epoch lasted from about 2.6 million to 11,700 years ago and is characterized by repeated glacial cycles and the emergence of modern humans.
- **Neocene**: This term is less commonly used in geology but generally refers to a time period that includes the late Tertiary and early Quaternary.

### Step 3: Identify the Relevant Epoch
Homo sapiens, or modern humans, are believed to have evolved during the **Pleistocene epoch**. This is when significant developments in human evolution occurred, including the appearance of Homo sapiens and their subspecies, such as Neanderthals.

### Step 4: Confirm the Answer
The question specifically asks when Homo sapiens evolved. Given that the Pleistocene is the epoch known for the emergence of modern humans, we can conclude that the correct answer is **Pleistocene**.

### Final Answer
Homo sapiens have evolved in the **Pleistocene** epoch.
