Tuesday; Gondwana;

Gondwana included most of the landmasses in today's Southern Hemisphere, including Antarctica, South America, Africa, Madagascar and the Australian continent, as well as the Arabian Peninsula and the Indian subcontinent, which have now moved entirely into the Northern Hemisphere.

The adjective Gondwanan is in common use in biogeography when referring to patterns of distribution of living organisms, typically when the organisms are restricted to two or more of the now-discontinuous regions that were once part of Gondwana, including the Antarctic flora. For example, the Proteaceae, a family of plants known only from southern South America, South Africa and Australia, are considered to have a "Gondwanan distribution". This pattern is often considered to indicate an archaic, or relict, lineage.

During the late Paleozoic, Gondwana extended from a point at or near the south pole to near the equator. Across much of Gondwana, the climate was mild. During the Mesozoic, the world was on average considerably warmer than today.

Gondwana was then host to a huge variety of flora and fauna for many millions of years. The laurel forest of Australia, New Caledonia and New Zealand have a number of other related species of the laurissilva de Valdivia, through the connection of the Antarctic flora as gymnosperms and deciduous angiosperm Nothofagus.

The sempervirens tree niaouli, it grows in Australia, New Caledonia and New Zealand. New Caledonia and New Zealand ecoregion are separated by continental drift from Australia 85 million years ago.

The islands still retain plants and animals that originated in Gondwana and spread to the southern hemisphere continents later. But there is strong evidence of glaciation during Carboniferous to Permian time.

The Gondwana Rainforests of Australia (formerly known as the Central Eastern Rainforest Reserves) include the most extensive areas of subtropical rainforest in the world, large areas of warm temperate rainforest and nearly all of the Antarctic beech cool temperate rainforest. Few places on earth contain so many plants and animals which remain relatively unchanged from their ancestors in the fossil record.
The Gondwana Rainforests of Australia were inscribed on the World Heritage List in 1986 (extended in 1994).
The Gondwana Rainforests of Australia were one of 15 World Heritage places included in the National Heritage List on 21 May 2007.

Global warming band aids?  A money spinner for some? 
The planet is fine, the people are fracked!  
The planet has always been in evolution, still is, who do we think we are? Are we better then any other living thing, because we have  developed a bigger brain? 
The planet will still  be here when all of us are gone. Evidence is still here.
