Question: The fossil record suggests that the last few million years featured the greatest biodiversity in history. However, not all scientists support this view, since there is uncertainty as to how strongly the fossil record is biased by the greater availability and preservation of recent geologic sections. Some scientists believe that corrected for sampling artifacts, modern biodiversity may not be much different from biodiversity 300 million years ago., whereas others consider the fossil record reasonably reflective of the diversification of life. Estimates of the present global macroscopic species diversity vary from 2 million to 100 million, with a best estimate of somewhere near 9 million, the vast majority arthropods. Diversity appears to increase continually in the absence of natural selection.
Is there an answer to this question: What appears increase continually in the absence of natural selection?

Answer: Diversity

Question: Endemic species can be threatened with extinction through the process of genetic pollution, i.e. uncontrolled hybridization, introgression and genetic swamping. Genetic pollution leads to homogenization or replacement of local genomes as a result of either a numerical and/or fitness advantage of an introduced species. Hybridization and introgression are side-effects of introduction and invasion. These phenomena can be especially detrimental to rare species that come into contact with more abundant ones. The abundant species can interbreed with the rare species, swamping its gene pool. This problem is not always apparent from morphological (outward appearance) observations alone. Some degree of gene flow is normal adaptation, and not all gene and genotype constellations can be preserved. However, hybridization with or without introgression may, nevertheless, threaten a rare species' existence.
Is there an answer to this question: What is another name for interbreeding?

Answer: unanswerable

Question: The city struck fortune in the late 18th century with the inventions and industrial activity of Eli Whitney, a Yale graduate who remained in New Haven to develop the cotton gin and establish a gun-manufacturing factory in the northern part of the city near the Hamden town line. That area is still known as Whitneyville, and the main road through both towns is known as Whitney Avenue. The factory is now the Eli Whitney Museum, which has a particular emphasis on activities for children and exhibits pertaining to the A. C. Gilbert Company. His factory, along with that of Simeon North, and the lively clock-making and brass hardware sectors, contributed to making early Connecticut a powerful manufacturing economy; so many arms manufacturers sprang up that the state became known as "The Arsenal of America". It was in Whitney's gun-manufacturing plant that Samuel Colt invented the automatic revolver in 1836. The Farmington Canal, created in the early 19th century, was a short-lived transporter of goods into the interior regions of Connecticut and Massachusetts, and ran from New Haven to Northampton, Massachusetts.
Is there an answer to this question: What was the nickname given to Connecticut due to the large number of arms manufacturers that arose in the state?

Answer: "The Arsenal of America"

Question: During the Middle Ages, the Eritrea region was known as Medri Bahri ("sea-land"). The name Eritrea is derived from the ancient Greek name for Red Sea ( Erythra Thalassa, based on the adjective erythros "red"). It was first formally adopted in 1890, with the formation of Italian Eritrea (Colonia Eritrea). The territory became the Eritrea Governorate within Italian East Africa in 1936. Eritrea was annexed by Ethiopia in 1953 (nominally within a federation until 1962) and an Eritrean Liberation Front formed in 1960. Eritrea gained independence following the 1993 referendum, and the name of the new state was defined as State of Eritrea in the 1997 constitution.[citation needed]
Is there an answer to this question: What was Ethiopia known as during the Middle Ages?
