    The 4.2 million-year-old fossil discovered in northeastern Ethiopia helps scientists fill in the gaps of how human ancestors made the giant leap from one species to another.
    4.2 million years is slightly older than 6,000 years..
    hat's because the newest fossil, the species Australopithecus anamensis, was found in the region of the Middle Awash -- where seven other human-like species spanning nearly 6 million years and three major phases of human development were previously discovered.

    "We just found the chain of evolution, the continuity through time," study co-author and Ethiopian anthropologist Berhane Asfaw said in a phone interview from Addis Ababa. "One form evolved to another. This is evidence of evolution in one place through time."

    so.. hmmmm... i can't think of a creationist response..
    "The key here is the sequences," White said. "It's about a mile thickness of rocks in the Middle Awash and in it we can see all three phases of human evolution."

    Modern man belongs to the genus Homo, which is a subgroup in the family of hominids. What evolved into Homo was likely the genus Australopithecus (once called "man-ape"), which includes the famed 3.2 million-year-old "Lucy" fossil found three decades ago.

    A key candidate for the genus that evolved into Australopithecus is called Ardipithecus. And Thursday's finding is important in bridging -- but not completely -- the gap between Australopithecus and Ardipithecus.

    In 1994, a 4.4 million-year-old partial skeleton of the species Ardipithecus ramidus -- the most recent Ardipithecus species -- was found about six miles from the latest discovery.

    "This appears to be the link between Australopithecus and Ardipithecus as two different species," White said. The major noticeable difference between the phases of man can be seen in Australopithecus' bigger chewing teeth to eat harder food, he said.
