Australia is a Continent of Evergreen Trees - Science

Science: Fagus Nothofagus gunnii is Australia's only temperate deciduous tree.
Australia has always been very hot. So hot in fact that only a few deciduous trees ever evolved. True some have been brought from other countries and the trees do grow in the cooler regions of Australia today. However, except for small pockets in the tropics evergreens predominate.

Trees which drop there leaves prefer a fixed unchanging climate. Australia is where the unexpected happens. Like the present where we are having a long hot end to summer and it is unusually wet. Evergreens can adapt and take off when conditions are favorable. When deciduous trees lose there leaves it could rain heavily, but they can no longer absorb the moisture. Conversely, putting out leaves when it dry for months on end is totally ineffective. Hold onto your leaves is the moto. When it rains evergreens are ready to push on to further growth.

Australia has one lonely temperate deciduous tree. And wouldn't you know it, the tree only grows in Tasmania, which gets the icy wind from Antarctica. These winds are always there in winter so the deciduous beech or Fagus ("Nothofagus gunnii") puts on a fabulous autumn leaf display then goes dormant during winter.

Natural History Museum Human Evolution Gallery

 The Human Evolution gallery at Natural History explores the origins of Homo sapiens by tracing our lineage back to when it separated from that of our closest living relatives, the bonobos and chimpanzees. Around 200,000 years ago, Africa was where modern humans developed. They have smaller faces and brow ridges, a chin that is more prominent than that of other ancient humans, and a brain case that is higher and more rounded. Modern human fossils from Israel (around 100,000 years old), Africa (around 195,000 years old), and Australia (around 12,000 years old) are among the casts on display. These fossils demonstrate that typical characteristics of modern humans evolved over time rather than emerging fully formed from Africa. They also suggest that at least two waves of people leaving Africa may have occurred, one about 100,000 years ago and the other about 60,000 years ago. We are all descendants of those who left during that second migration wave outside of Africa. Source: Natural...

Study of Tooth Enamel Indicates Neanderthal Diet Was Carnivorous

 A new study on Neanderthal dietary practices has just been published in the journal PNAS by researchers from the French National Centre for Scientific Research (CNRS) and several German scientific institutions. They were able to determine that a Neanderthal who lived in a cave on the Iberian Peninsula during the Middle Paleolithic period (50,000 years ago) ate exclusively carnivorous food using a newly developed method for studying the chemical signatures of ancient tooth enamel. This isn't the first study to find this, either. Despite this, it is a one-of-a-kind and significant discovery because it was made through the development of a novel analytical method that could be used to learn more about the diet and way of life of Neanderthals who lived in other parts of Eurasia in the distant past.   To investigate the diet and eating habits of Neanderthals, numerous research projects have been initiated. However, they have resulted in contradictory outcomes. The CNRS researchers...
