What contribution did alexander graham bell make to the industrial era?

exander Graham Bell is best known for his invention of the telephone, for which he received his first patent in 1876. Despite the hundreds of lawsuits that would challenge his claim to the invention, none would prove successful. Born in Scotland and later becoming a U.S. citizen, Bell spent his life in pursuit of scientific discovery, and despite his myriad accomplishments as a scientist and inventor, he saw himself first and foremost as a teacher of the deaf, dedicating the majority of his work to that field.

He contributed to the Industrial Revolution by inventing "Telephone".

Explanation:

During the Industrial Revolution, Alexander Graham Bell invented the telephone. Alexander Graham Bell proves talking into the telephone employing a model archetype in the year 1876. The invention of the telephone had a significant impact on society due to the fact that it reduced the time a piece of information took to reach to a particular person or group.

answer:   migrations were important in the neolithic period. "two major migrations passing through southeastern europe were confirmed by the means of archaeo-genetic studies."

the first migration was the early neolithic period -- 6,000 before common era (bce) -- when the first farmers, from anatolia -- asia minor -- spread through europe. the second migration occurred during the early bronze age (3,000-2,500 bce) when the so-called "steppe population," from the eurasian steppe, replaced much of northern europe's previous population.

the first farmers of northern and western europe passed through southeastern europe with limited hunter-gatherer genetic admixture, which occurs when two or more previously isolated populations begin interbreeding. however, some groups that remained mixed extensively -- without the male-biased, hunter-gatherer admixture that prevailed later in the north and west, according to latest discoveries. southeastern europe continued to be a nexus between east and west, with intermittent genetic contact with the steppe people up to 2,000 years before the migrations that replaced much of northern europe's population.

"in some places, hunter-gatherers and incoming farmers seem to have mixed very quickly," says iain mathieson, a geneticist at the university of pennsylvania, who was first author of the paper. "but, mostly, the two groups remained isolated, at least for the first few hundred years. these hunter-gatherers had been living there for thousands of years, and it must have been quite a shock to have these new people show up -- with a completely different lifestyle and appearance."
