Answer:Primates are characterized by relatively late ages at first reproduction, long lives and low fertility. Together, these traits define a life-history of reduced reproductive effort. Understanding the optimal allocation of reproductive effort, and specifically reduced reproductive effort, has been one of the key problems motivating the development of life history theory. Because of their unusual constellation of life-history traits, primates play an important role in the continued development of life history theory. In this review, I present the evidence for the reduced reproductive effort life histories of primates and discuss the ways that such life-history tactics are understood in contemporary theory. Such tactics are particularly consistent with the predictions of stochastic demographic models, suggesting a key role for environmental variability in the evolution of primate life histories. The tendency for primates to specialize in high-quality, high-variability food items may make them particularly susceptible to environmental variability and explain their low reproductive-effort tactics. I discuss recent applications of life history theory to human evolution and emphasize the continuity between models used to explain peculiarities of human reproduction and senescence with the long, slow life histories of primates more generally.

Answer:
Jade is unique when compared with other gems because in the excerpt it says "The value of jade to the Mayan people went far beyond its use as an art material. It had deep spiritual significance as well. The Mayan people saw a connection to water and plants in the mineral’s green color. Some evidence suggests that Mayan royalty associated jade with life and death. It was said that a small bead of jade placed on the tongue would absorb the spirit of a dying royal." So this shows that jade was big part of their culture. The event in recent history changed geologist’s ideas about where the Mayans and earlier people found the jade they used in their artwork is when Hurricane Mitch devastated Guatemala and Honduras in 1999, heavy rains and flooding exposed many previously covered deposits of jade. This included a large vein of a rare blue-green variety of jadeite that had been used by the Olmec people.

Answer:
Dred Scott v. Sandford, 60 U.S. (19 How.) 393 (1857), was a landmark decision of the U.S. Supreme Court in which the Court held that the Constitution of the United States was not meant to include American citizenship for black people, regardless of whether they were enslaved or free, and therefore the rights and privileges it confers upon American citizens could not apply to them.[2][3] The decision was made in the case of Dred Scott, an enslaved black man whose owners had taken him from Missouri, which was a slave-holding state, into the Missouri Territory, most of which had been designated "free" territory by the Missouri Compromise of 1820. When his owners later brought him back to Missouri, Scott sued in court for his freedom, claiming that because he had been taken into "free" U.S. territory, he had automatically been freed, and was legally no longer a slave. Scott sued first in Missouri state court, which ruled that he was still a slave under its law. He then sued in U.S. federal court, which ruled against him by deciding that it had to apply Missouri law to the case. He then appealed to the U.S. Supreme Court
