What do artifacts tell us about the lives of early hominids?

Artifacts tell us how early hominids lived. If an archeologist found some new type of bones that could mean 1.) That there was another older species of hominids 2.) That there is more artifacts around that area. Hominids held a special place in history. The only way to understand their culture or how they lived millions of years ago was by their preserved tools or their extra ordinarily large bones. The tribe homo habilis was only the second oldest hominid tribe founded, with a small amount of brain they came up with ideas that we still use today in 2011. The bones coming from Neanderthals are still the largest in history, the only tribe who survived the ice age... then came Cro- magnons (in other words us), who finally took over the land prohibited by Neanderthals. Artifacts by Neanderthals could have been a sign that he/she belonged to a certain clan or it might be the meaning of his/her name. How scientist really got information was by early hominids bones, showing how strong, what sicknesses he/she might have had while he/she was still alive, if he/she was a male or female and how he/she might have died. Another way the scientists might have gotten information is from the teeth because you could tell what they've eaten, how healthy and strong he/she was and if he/she used his/her teeth for creating tools. So what do artifacts tell us about the lives of early hominids? Artifacts held a special place in history the same as early hominids.
