Based on the information provided and general knowledge about the fossil record, let's evaluate each statement:
1. **The complexity of organisms appeared to decrease around four hundred million years ago.**
- This statement is likely false. Generally, the fossil record shows that complexity has increased over time, particularly during the Cambrian explosion and afterward.
2. **The fossil record suggests that mammals (not listed) must have first appeared six-hundred million years ago.**
- This statement is false. Mammals are believed to have appeared around 200 million years ago, not 600 million years ago.
3. **According to the data, the first humans most likely appeared twenty-five million years ago.**
- This statement is false. The first ancestors of modern humans are thought to have appeared around 2 to 3 million years ago, not 25 million years ago.
4. **The first reptiles appeared sometime between amphibians and primates according to the fossil record.**
- This statement is true. Reptiles first appeared in the fossil record during the late Carboniferous period (about 320 million years ago), while primates appeared much later.
Based on this analysis, the true statement is: **The first reptiles appeared sometime between amphibians and primates according to the fossil record.**
