The oldest known fossil among the Eutheria ("true beasts") is the small shrewlike Juramaia sinensis, or "Jurassic mother from China", dated to 160 million years ago in the Late Jurassic. A later eutherian, Eomaia, dated to 125 million years ago in the Early Cretaceous, possessed some features in common with the marsupials but not with the placentals, evidence that these features were present in the last common ancestor of the two groups but were later lost in the placental lineage. In particular:
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what time period did early animals share some features with marsupials?
Ah, so.. 125 million years ago

The deeper ancestral demography of Bermuda's population has been obscured by the ethnic homogenisation of the last four centuries. There is effectively no ethnic distinction between black and white Bermudians, other than those characterising recent immigrant communities. In the 17th century, this was not so. For the first hundred years of settlement, white Protestants of English heritage were the distinct majority, with white minorities of Irish (the native language of many of whom can be assumed to have been Gaelic) and Scots sent to Bermuda after the English invasions of their homelands that followed the English Civil War. Non-white minorities included Spanish-speaking, free (indentured) blacks from the West Indies, black chattel slaves primarily captured from Spanish and Portuguese ships by Bermudian privateers, and Native Americans, primarily from the Algonquian and other tribes of the Atlantic seaboard, but possibly from as far away as Mexico. By the 19th century, the white ethnically-English Bermudians had lost their numerical advantage. Despite the banning of the importation of Irish, and the repeated attempts to force free blacks to emigrate and the owners of black slaves to export them, the merging of the various minority groups, along with some of the white English, had resulted in a new demographic group, "coloured" (which term, in Bermuda, referred to anyone not wholly of European ancestry) Bermudians, gaining a slight majority. Any child born before or since then to one coloured and one white parent has been added to the coloured statistic. Most of those historically described as "coloured" are today described as "black", or "of African heritage", which obscures their non-African heritage (those previously described as "coloured" who were not of African ancestry had been very few, though the numbers of South Asians, particularly, is now growing. The number of persons born in Asian countries doubled between the 2000 and the 2010 censuses), blacks have remained in the majority, with new white immigration from Portugal, Britain and elsewhere countered by black immigration from the West Indies.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What groups of Bermudians is there an ethnic distinction between?
Ah, so.. unanswerable

The new head of state, Ibrahim Babangida, declared himself president and commander in chief of the armed forces and the ruling Supreme Military Council. He set 1990 as the official deadline for a return to democratic governance. Babangida's tenure was marked by a flurry of political activity: he instituted the International Monetary Fund's Structural Adjustment Program (SAP) to aid in the repayment of the country's crushing international debt, which most federal revenue was dedicated to servicing. He enrolled Nigeria in the Organisation of the Islamic Conference, which aggravated religious tensions in the country.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did Babangida set up to help pay Nigeria's national debt?
Ah, so..
International Monetary Fund's Structural Adjustment Program
