A scientist found a hominid fossil that appeared anatomically to be that of Homo habilis. It was found, however, in a rock layer that suggests it is only about 150,000 years old. Based on this, he wants to publish a paper asserting the fossil shows that Homo habilis lived much longer than thought and was contemporary with early Homo sapiens. Which of the following should he do to build a stronger case before he publishes?

Which of the following should he do to build a stronger case before he publishes? 

 Convince other scientists to support his conclusions about the fossil. 

 Look for evidence of cave paintings at the site where he found the fossil. 

 Find out how old the fossil actually is using radioactive dating. 

 Look for similar fossils in the same rock strata.
