Extract:

"Scientists have unearthed the jawbone of what they claim is one of the very first humans.

The 2.8 million-year-old specimen is 400,000 years older than researchers thought that our kind first emerged.

The discovery in Ethiopia suggests climate change spurred the transition from tree dweller to upright walker."

Jaw bone fossil discovered in Ethiopia is oldest known human lineage remains

Extract:

"A lower jaw bone and five teeth discovered on a hillside in Ethiopia are the oldest remains ever found that belong to the genus Homo, the lineage that ultimately led to modern humans.

Fossil hunters spotted the jaw poking out of a rocky slope in the dry and dusty Afar region of the country about 250 miles from Addis Ababa.

The US-led research team believes the individual lived about 2.8m years ago, when the now parched landscape was open grassland and shrubs nourished by tree-lined rivers and wetlands.

The remains are about 400,000 years older than fossils which had previously held the record as the earliest known specimens on the Homo lineage."

More assumptions... Well, this is the oldest until the next oldest fossil is found. How do they know that its the first human? They don't, they only assume.
