Answer:
The Tasmanian devil introduction:
Explanation:
The Tasmanian devil (Sarcophilus harrisii) is threatened with extinction because of a contagious cancer known as Devil Facial Tumor Disease. The inability to mount an immune response and to reject these tumors might be caused by a lack of genetic diversity within a dwindling population. Here we report a whole-genome analysis of two animals originating from extreme northwest and southeast Tasmania, the maximal geographic spread, together with the genome from a tumor taken from one of them. A 3.3-Gb de novo assembly of the sequence data from two complementary next-generation sequencing platforms was used to identify 1 million polymorphic genomic positions, roughly one-quarter of the number observed between two genetically distant human genomes. Analysis of 14 complete mitochondrial genomes from current and museum specimens, as well as mitochondrial and nuclear SNP markers in 175 animals, suggests that the observed low genetic diversity in today's population preceded the Devil Facial Tumor Disease disease outbreak by at least 100 y. Using a genetically characterized breeding stock based on the genome sequence will enable preservation of the extant genetic diversity in future Tasmanian devil populations.

Answer:
Explanation:It is different to the system in the Middle Ages, usually called feudalism, where control of land and the workers who were bonded to that land was the key to making wealth. ... So the transatlantic slave trade and plantation wealth were the major causes of the growth of capitalism in Europe.
Answer:
he was a South African cardiac surgeon who performed the world's first highly-publicized heart transplant and the first one in which the patient regained consciousness.
Explanation:
At the end of the Civil War two very different plans for reconstructing the nation were offered. Had Lincoln lived perhaps history would have different. The assassination of Lincoln, however, left the vulnerable Andrew Johnson, a Southerner and former slave owner with no college education, President. Could he live up to Lincoln's ideals? Would he be allowed the opportunity? That is the question.
After the Civil War congress was controlled by a group called the "Radical Republicans." Lincoln was able to control them and had proposed a plan for reconstruction that looked to treating the South more like a lost brother returning home. Lincoln looked to reconstruction as a time of healing. The Radical Republicans, however, looked at reconstruction as an opportunity to teach the South a lesson and to punish them. In 1866 Congress passed theWade-Davis Bill which called for rather draconian Reconstruction measures. Lincoln vetoed the bill but thedebate raged.
Lincoln would have been able to control the Radical Republicans, at least that is the conventional wisdom. Lincoln's death, however, left a void in leadership. The new President, Andrew Johnson, was a southerner. As you can imagine this bitter irony was not lost on the Radical Republicans who hated him even before he was President. Johnson proposed a plan similar to Lincoln's. Suffice it to say, congress was not amused. The relationship between Lincoln and Congress soured quickly.
