The African Origin of Homo sapiens: Genetic History of Human Migration

Modern humans — Homo sapiens — are the only surviving species of the genus Homo. Despite our visible diversity, all living humans share a recent common evolutionary origin in Africa. This conclusion is supported by palaeoanthropology, archaeology, and population genetics.

The study of ancient fossils, archaeological cultures, and genetic markers — including mitochondrial DNA, Y-chromosome lineages, and genome-wide variation — has allowed scientists to reconstruct the major stages of human origins, migrations, and adaptation. 

For readers of Science & Life, this is not only a story about the distant past. It is also a story about the unity of humankind, the movement of ancient populations, the power of scientific evidence and the danger of oversimplified racial myths.

The Art of Turning Rejection into Billions: How Sara Blakely Built Spanx from a Pair of Cut-Off Tights

 

Special analytical material by the 100%NEWS.TV Editorial Department

Imagine a classic picture of apparent hopelessness: exhausting Florida heat, a heavy business suit, and an endless line of doors being closed before a young saleswoman could finish her pitch. For seven years, Sara Blakely sold fax machines door to door. Before that, she had twice failed the LSAT, the law-school admission test in the United States, and had even failed to secure a role as Goofy at Walt Disney World because she was not tall enough for the costume.

At first glance, this looked like the ordinary biography of a person moving from one disappointment to another. Yet two decades later, Forbes would place that same woman on its cover and describe her as the youngest self-made female billionaire. By the age of 41, the company she had created — Spanx — had become a billion-dollar business. It had been built without external venture capital, without an elite business-school background, and without family connections inside the closed world of fashion and retail.

Dr Olga Azarova: Five Scientific Truths About Your Inner Strength

“Why are some people so lucky, while others are not?” “I will try once more, and then decide whether to continue.” “Maybe I am simply not as strong as others.” “Perhaps we have a different mentality.” “Why does life give opportunities to some people and not to others?”

Have you heard such phrases before? Of course you have. They fill the air around us, because the world often contains more voices of complaint than voices of courage. Yet biology tells a different story. From the very beginning, life is not built on weakness. Life begins with energy, selection, interaction, movement and the extraordinary capacity to overcome resistance.

Dr. Olga Azarova: Full Potential begins from signs of viability

An excerpt from the book by renowned entrepreneur and innovator Dr Olga Azarova, The Full Potential of the Human Being: The Eight Intelligences, offers a clear conceptual foundation for understanding what it means to be “alive”. As an introduction to the methodology of MINIBOSS & BIGBOSS BUSINESS SCHOOLS, this text presents a broader vision of life itself — and of the kind of education humanity needs in order to understand, develop and consciously manage life for the benefit of the individual and the Planet.

A little science is useful for all of us, isn’t it? Yes, life is a remarkable journey — one that human beings instinctively wish to extend for as long as possible. Yet within this journey, some processes may be prolonged, while others may be shortened. In other words, the quality and duration of life can be consciously influenced if we understand three fundamental questions: who are we, how do we function, and how can we manage our organism and, consequently, our life?
