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.

An archaeologist was able to determine the sites by the bricks similar but was old found in the area where they lay railroads.
<u>Explanation:</u>
- While railroads were constructed in Pakistan the engineers were searching for ballast which is used for railroad construction to drain water from the railways.
- Archaeologists later discovered the settlements along the Indus river, thousands of clay pellets with writings older than Sumerian, combs, pottery, seals, urban, plans with grid pattern during the excavation process.
- Both Harappa and Mohenjo Daro is a part of Indus Valley Civilization. The period of the excavated materials and artifacts is determined by the process name called Radio-Carbon Dating in which the age of the carbon can be accessed.
Answer:
Long staple cotton was profitable because the cotton fibers could be easily separated from the seeds. ... While reducing the number of slaves needed to grow cotton the cotton gin greatly increased the areas where cotton could be profitably grown. This increased the demand for slaves.
