Explanation:

The fact of living with the same group of people for many hours usually generates emotional ties, whether of trust, respect or even friendship. These ties bring a series of advantages and disadvantages, not only for employees, but also for the employer.

It is necessary to remember that it is not easy to manage any type of personal relationships within the work, and this includes the friends within this space. Many times, if there is too much trust, the line between professionalism and familiarity can become diffuse, creating a lack of formality or causing personal conflicts to transcend the workplace. In addition, it can make it difficult to establish hierarchies and superiority relations inherent in the company, and also pose a difficulty for those colleagues who do not enjoy this type of intimacy.

early human migrations are the earliest migrations and expansions of archaic and modern humans across continents and are believed to have begun approximately 2 million years ago with the out of africa migration of homo erectus. this initial migration was followed by other archaic humans including h. heidelbergensis, which lived around 500,000 years ago and was the likely ancestor of both denisovans and neanderthals. early hominids were said to have "crossed land bridges that were eventually covered in water" .

within africa, homo sapiens dispersed around the time of its speciation, roughly 300,000 years ago.the "recent african origin" paradigm suggests that the anatomically modern humans outside of africa descend from a population of homo sapiens migrating from east africa roughly 70,000 years ago and spreading along the southern coast of asia and to oceania before 50,000 years ago. modern humans spread across europe about 40,000 years ago.

the migrating modern human populations are known to have interbred with local varieties of archaic humans, so that contemporary human populations are descended in small part (below 10% contribution) from regional varieties of archaic humans.

after the last glacial maximum, north eurasian populations migrated to the americas about 20,000 years ago. northern eurasia was peopled after 12,000 years ago, in the beginning holocene. arctic canada and greenland were reached by the paleo-eskimo expansion around 4,000 years ago. finally, polynesia was peopled after 2,000 years ago, by the austronesian expansion.
