It’s very possible—and, according to this article, cave men (and women) are alive today:
Evolutionary stereotypes of the first humans as primitive “Stone Age” cave men who had not yet evolved agriculture just do not square with the Bible’s account of history. The Bible says that in Adam’s day, people “worked the soil” (Genesis 4:2—following the events of 2:15 and 3:17), forged bronze and iron tools (4:22) and made and played musical instruments (4:21). There never was a “Stone Age”! (Nor the evolutionary-defined “Bronze Age” or “Iron Age” for that matter.)
