concept of eugenics were widely discussed as knowledge about genetics advanced significantly. Endeavors such as the Human Genome Project made the effective modification of the human species seem possible again (as did Darwin’s initial theory of evolution in the 1860s‚ along with the rediscovery of Mendel’s laws in the early 20th century). The difference at the beginning of the 21st century was the guarded attitude towards eugenics‚ which had become a watchword to be feared rather than embraced.

A. Evolution and Behavior 1. Study microevolution by viewing domestication and natural selection in the wild. 2. Domestic dogs attack prey differently than their ancestral wolves do due to behavioral selection 3. In domesticating foxes‚ you are selecting for neotenous traits and a suppressed adrenal gland that made the foxes less aggressive 4. Natural disasters or major ecological changes are good examples of looking at microevolution 5. When studying behavior

Hyperthyroidism‚ otherwise known as thyrotoxicosis‚ is a disease where the thyroid is overactive. Although the thyroid is not a large-sized gland located on the front of the neck‚ it is a big part of the endocrine system that produces a hormone called the thyroid-stimulating hormone. These hormones play a role in regulating different parts in the body‚ such as metabolism‚ body temperature‚ and bone growth (N1). It even plays a role in how your heart beats! The thyroid-stimulating hormone also helps
