Answer:
When the calcium level is high in the bloodstream, the thyroid gland releases calcitonin. Calcitonin slows down the activity of the osteoclasts found in bone. This decreases blood calcium levels. When calcium levels decrease, this stimulates the parathyroid gland to release parathyroid hormone.

1. 15,000 years ago the humans were still hunter-gatherers. Their daily lives were largely based around one thing, finding enough food to survive through the next few days. This means that they had to constantly be on the move, be it for hunting animals, or for finding rich places with eatable plants. There was lot of walking, running, and scouting involved every day. It was a lifestyle of ''living through the day''.
2. During this period of time, the diet of the humans was consisted of animals they hunted, fish, and plants. There were differences from region to region though, so the people that lived along the coastline based their diet on marine animals, the ones that were living in colder regions were eating mostly meat, while the ones living in forested areas or grasslands had combination of plants and meat. The lifestyle in general was moving from place to place, be it on a daily basis, weakly, or seasonally, depending on the conditions. Some of these people were making small shelters, some of which were retractable and they were moving them with them, while others were using caves.
3. There are many difference between the forager peoples and the agriculturalists. The foragers were nomads, thus they were moving very often from one place to another, while the agriculturalists were having a settled lifestyle. The nomads very often had bad injuries which were often fatal, usually because of hunting, while the agriculturalists had much better health because they had much safer lifestyle. The foragers were not able to produce their own food, but instead they were relying on mother nature, while the agriculturalists were producing their own food and had the food problem solved.
Answer:
The correct answer will be-<em> </em><em>Homo neanderthalensis</em>
Explanation:
The closest ancestor of modern humans which evolved in the Pleistocene age which was around 7 lakh to 3 lakh years is the <em>Homo neanderthalensis</em> or Neanderthals.
The Neanderthals became extinct around 12,000-10,000 years ago by competitive <em>Homo sapiens</em>.
The specimens of Neanderthals are collected from the central and Western Asia and parts of Europe and showed approximately the same cranial capacity which is around 1450-1500 cc.
Thus, <em>Homo neanderthalensis</em> is the correct answer.
