Microfossil finds have been firmly established at about 3.5 Ga (giga annee=109 years), but no rocks older than about 4.0 Ga have been demonstrated, leaving the history of the first 0.6 Ga missing. This gap has been filled by models of the solar system. The origin term of the ocean, atmosphere, and much crustal material apparently lies in a heavy rain of comets, subsequent to the catastrophic Moon-forming event. The earliest microfossils are those of the Apex chert in Australia, about 3.5 Ga old. ‘Prebiotic’ simulations of possible biochemistry have made some progress in recent years, but many obstacles remain, and there is no agreement as to the course of development. The ‘ribose nucleic acid (RNA) World’, aboriginal ‘clay genes’, and catalysis on iron-sulfide precipitates are not ruled out. The search for the ‘last common ancestor’ has reached a point between the Bacteria and the Archaea. It is possible that this organism may have been a thermophile, similar to many modern hot spring organisms. But it is likely to have been an autotroph, and a late development after the true origin of life. Even more speculative are suggestions about the origins of metabolic sequences, in particular the origin of the genetic code. Since all modern organisms share this code (and many other things), there had to be a long history of development during the blank period of Earth history.


Slag Dobbelsteen, Rotterdam, The Netherlands

Slag Dobbelsteen is an artificial area near the planned Maasvlakte 2 in Rotterdam. It’s used for a wide variety of activities, like nude swimming, wind energy, surfing or diving in the inner sea (created by huge concrete dices functioning as wave breaker) to see the new biological entities living in the coolingwater of the factories of the port of Rotterdam. The Happy Shrimp Farm is using the warm water to breed shrimps. It is the first tropical shrimp farm in Europe and an example of a new eco-industrial company in the port of Rotterdam that benefits the economy and environment.
The greenhouse-enclosed farm is located on the dunes near the city of Rotterdam. It is co-sited near a power plant of E.ON Benelux utilizing the waste heat for warming the farm. You can also look out for new animals or species settling down in the area. Check this site for the statistics and spotted organisms.
