Rather than modern humans rapidly replacing Neanderthals, there seems to have been a more complex picture «characterised by a biological and cultural mosaic that lasted for several thousand years».
Neanderthals were generally only 12 to 14 cm (4 1/2 — 5 1/2 in)
shorter than modern humans, contrary to a common view of them as «very short» or «just over 5 feet».
Manot is thus 10,000 years
older than any modern human found in Europe, and about 5 - 10,000 years younger than the point when geneticists predict the appearance of our direct ancestors in Africa.
The 1918 virus (r1918) activated many more mouse genes involved in the immune
system than a modern human flu virus (Tx91) and two hybrids between a modern virus and the 1918 strain.
Similar in size and weight to a modern human, and with humanlike hands and feet, the new species has a braincase more similar in size to earlier ancestors living two million to four million years ago, as well as shoulders, pelvis, and ribcage more closely resembling earlier
hominins than modern humans.
The barium levels in a Neanderthal child's molar indicate its mother stopped breastfeeding at 14 months — more than a year earlier than modern humans
The numbers represent a lower limit, as Neandertals and other extinct hominins likely had more muscle
mass than modern humans.
It suggests they matured
faster than modern humans, who tend to be weaned at 30 months in hunter - gatherer and agrarian societies.
«The Denisovans were spread across an extraordinarily wide [north - south] geographic and ecological zone,» says Stoneking, «wider than any hominin
other than modern humans — wider than Neanderthals.»
More insightful and self -
reflective than modern humans, with fantastic memories and a penchant for dreaming, the Boskops may have had «an internal mental life literally beyond anything we can imagine.»
Teeth from these diminutive individuals suggest they belonged to a unique species rather
than a modern human with a growth disorder, as previously suspected
DNA from Denisovans suggests they lived in Siberia for millennia and were more genetically diverse than Neandertals, but less diverse than modern humans
The researchers caution that it's impossible to draw broad conclusions about Neandertal life histories from this one sample, such as whether Neandertals weaned their children earlier or
later than modern humans who lived at the same time, or whether Neandertal children grew up faster, as some earlier studies have suggested — questions that could heavily bear on why Neandertals could not keep up with modern humans in the survival sweepstakes.
Although Neanderthals had broader
bodies than modern humans, he added, their brain to overall body size ratio was still larger than that of our species.
Scientists have found the first major evidence that Neanderthals,
rather than modern humans, created the world's oldest known cave paintings — suggesting they may have had an artistic sense similar to our own.
From this study [subscription required], Zollikofer concludes that Neanderthal mothers may have had their first child, on average, when they were a year or two
older than modern humans and that their time between pregnancies was probably longer.

And, it is certainly not true that H. erectus has «an appropriately smaller head (and brain size)»
than modern humans.
Neanderthals were stockier and shorter
than modern humans, with no chin and backwards sloping foreheads.
