history of thylacine is the chronicle of an announced death. Recent genetic analyzes have confirmed that the thylacine population in Tasmania had very low genetic diversity prior to its extinction, possibly as a result of its geographic isolation from mainland Australia approximately 10,000 years ago. Their disappearance was the result of an explosive cocktail of relentless human persecution, competition with dogs, loss of habitat and an epidemic that decimated the population in the 1920s. A hundred years have passed since the Museum acquired the fantastic thylacine specimen that it exhibits in its rooms. It was bought from the London store of Rowland Ward Ltd., which was the most famous in Europe at the time and known as “the jungle.” The invoice, dated December 28, 1917, is kept in the MNCN Archive. 618 pesetas were paid for this piece. of the time

at the current exchange rate). Although thylacine no longer Somalia Email List exists, the interest generated by this species remains intact. Currently there is an international database of thylacine specimens, which gathers information on all the specimens that exist in collections from all over the world, including that of the MNCN. There is also a project to recover the genome of thylacines that are preserved in museums and another project to explore the possibility of cloning it using genetic material from preserved tissues. There is also an excellent online museum The Thylacine Museum that we invite you to visit if you want to get to know this fantastic animal better.A study carried out by researchers from the Higher Council for Scientific Research (CSIC) has discovered that the most efficient molecular tools that exist in nature to degrade lignin, a polymer that gives rigidity to plant

tissues and allows plants to grow tall, they have appeared several times independently during the evolution of wood-degrading fungi. The results of the study have been published in the journal Proceedings of the National Academy of Sciences (PNAS) . “The degradation of this polymer is a key step in the recycling of carbon from plant ecosystems. Access to other plant polymers, such as cellulose and hemicellulose, depends on lignin, which together with the former constitute the largest reservoir of organic carbon that exists on the earth’s surface ”, explains CSIC researcher Francisco Javier Ruiz Dueñas, of the Center for Biological Research. Lignin is one of the most abundant polymers that exists in nature and its appearance was decisive for plants to colonize terrestrial ecosystems. In addition to providing rigidity to plant tissues, it gives the ability to grow in height,
