Answer:
Africa
Explanation:
The earliest finding of modern Homo sapiens skeletons come from Africa. They date to nearly 200,000 years ago in the African Continent.
Current data suggest that modern humans evolved from archaic humans primarily in East Africa. A 195,000 year old fossil from the Omo 1 site in Ethiopia shows the beginnings of the skull changes that we associate with modern people, including a rounded skull case and possibly a projecting chin.
A 160,000 year old skull from the Herto site in the Middle Awash area of Ethiopia also seems to be at the early stages of this transition. It had the rounded skull case but retained the large brow ridges of archaic humans. Somewhat more advanced transitional forms have been found at Laetoli in Tanzania dating to about 120,000 years ago. By 115,000 years ago, early modern humans had expanded their range to South Africa and into Southwest Asia (Israel) shortly after 100,000 years ago. There is no reliable evidence of modern humans elsewhere in the Old World until 60,000-40,000 years ago, during a short temperate period in the midst of the last ice age
An age-related change in the nervous system that can adversely affect nutritional status is decreased taste perception, hearing loss and vision loss. Aging refers to a multidimensional process in humans, the process of physical, and psychological, and social changes. As a population, older adults are more prone to age-related diseases, functional impairment, and physical inability that nay interfere with the maintenance of a good nutritional status.
Answer:
destruction of native species
Explanation:
Invasive species are destructive. They ruin ecosystems in which everything has a role, and all niches are full. With an invasive species, such as Pablo Escobar's hippos. A drug lord of South America had several hippos transported to his estate. Even after he died, the hippos flourished in South America. This was a perfect environment for the hippos as they had plenty to eat, and no threat where in Africa they would compete with lions, crocodiles and such. But the hippos just kept multiplying, eating food otherwise for native species, and destroyed the land with their size. The hippos endangered several species in the surrounding area at the cost of their easy living, as well as the people around.
Long story short, destruction of native species.
