Professor Chris Stringer, head of human origins at London's Natural History Museum, said: "Both were apparently stone tool-makers, but one possibility is that the larger and perhaps more mobile erectus species was an active hunter, while habilis scavenged or caught small prey."
It is most likely that both species evolved from a common ancestor.

Its the common ancestor bit that's important DCE, that's evolution.
FOSSIL EVIDENCE BACKFIRES
The evidence from fossils, the remains of living things dug up from the earth, also has backfired on evolutionists.
They had hoped that after more than a century of searching, they would have found numerous in-between fossils linking the various types of once-living things together in an unbroken chain. But the abundant fossil evidence now available has completely shattered this hope.
Zoologist Coffin says: The fossils, evidences of the life of the past, constitute the ultimate and final court of appeal, because the fossil record is the only authentic history of life available to science.
And what does the record show?
Does it agree with evolution?
Coffin answers: It does not, it tells us that plants and animals were created in their basic forms.
The basic facts of the fossil record support creation, not evolution.
Dr. D. B. Gower, biochemist from London University, also confirms that the story of the fossils agrees with the account of Genesis (in the Bible). He says that in the oldest rocks we do not find a series of fossils covering the gradual changes from the most primitive creatures to developed forms, but, rather, in the oldest rocks, developed species suddenly appeared. He also observed that between every major type of plant and animal there was a complete absence of intermediate fossils.
Thus, after more than a century of digging up millions of fossils, the record confirms that life-forms were created according to their kinds.Gen. 1:11, 12, 21, 24.
RETREAT ON MANS HISTORY
Recent discoveries of human fossils have caused a retreat, also, regarding mans supposed evolutionary history. These discoveries have made a shambles of the evolutionary tree, the hypothetical lineup of apelike creatures assertedly leading to man.
Because of these recent discoveries, the Boston Globe declared: Every single book on anthropology, every article on the evolution of man, every drawing of mans family tree will have to be junked.
It also means we have had our ancestors mixed up.
What has caused this retreat?
The discovery of modern-type human fossils believed to be older than the supposed apemen from which they were alleged to have come.
One of these apelike creatures, labeled Australopithecus by scientists, was once even hailed by some as being the missing link between humans and apes.
But according to scientific sources the new evidence has shown this to be impossible. The New York Times reported: The new fossils provided conclusive evidence that Australopithecus, an extinct species once thought to be transitional between ape and man, was, instead, a contemporary of early man that became an evolutionary dead end.
The truth is that humans, too, were created according to their kind. That is why no links have ever been found between man and beast. It is also why none ever will be found. The huge gap will always remain, put there by the Creator to keep man and beast distinct.
Anthony Ostric, a professor of anthropology from Indiana, told a congress of scientists that the evidence shows that man has remained essentially the same since he first appeared. He declared: It is not possible to see how biological, social or cultural forces or processes could transform any kind of prehuman anthropoid or near-man into homo sapiens. He observed that mans unique biophysical and socio cultural nature appears to represent an unbridgeable abyss separating him from all other animals.
Plainly, the evidence accumulated over many decades has forced evolution to retreat on many fronts.
Facing the facts honestly leads to only one conclusion. As the Bible long ago declared: Know that Jehovah is God. It is he that has made us, and not we ourselves.Ps. 100:3.
