Recent common ancestor based on chromosomes 1-22February 26, 2026Interpreting the recent common ancestor of human autosomes 1-22 from a genomic perspective, explaining DNA recombination, mutation and ancestral fragment inheritance, and popularizing the common ancestor time in the sense of human genetics.
Modern man in the sense of anatomyFebruary 26, 2026What is modern man in the sense of anatomy? This paper systematically introduces the origin and characteristics of late Homo sapiens from the definition, key fossils (Jebel Iro, Omo, Herto), age and evolutionary diffusion.
Late Paleolithic RevolutionFebruary 28, 2026About 50000 years ago, our race experienced something very special: just as Athena in Greek mythology injected soul into mankind, mankind suddenly possessed unprecedented figurative artistic creativity. This event, known as the "Late Paleolithic Revolution", is a watershed in the history of human evolution.
Orina CultureMarch 4, 2026What is Aorina culture? Age, distribution, tools, murals and sculptures (Chauvius Caves, Lions, Hochler Fellows Venus).
Denisovans mixed with modern peopleMarch 12, 2026Denisovans are an ancient human species discovered through DNA analysis. They coexisted with Neanderthals and modern humans and interbred with both. This paper provides a detailed analysis of gene flow, the EPAS1 gene on the Tibetan Plateau, the Xiahe mandible, and the distribution of ancestral components across global populations.
The Hobbit ExtinctionMarch 12, 2026Who were the Flores (Hobbits)? Why were they short? When did they become extinct? This article describes the fossils, evolution and extinction of this mysterious dwarf human.
Neanderthals mixed with modern humansFebruary 27, 2026Are modern people mixed with Neanderthals? How many Neanderthals genes do Europeans, Asians and Africans each contain? This article understands the history of gene exchange and evolution between humans and Neanderthals.
Y chromosome AdamMarch 4, 2026What is Y chromosome Adam? This article explains the paternal inheritance of Y chromosome, molecular clock age, African origin of 120000 year, and the difference between it and mitochondrial Eve.
The earliest modern humans outside AfricaMarch 4, 2026Where are the earliest modern fossils outside Africa and how many years ago? This article introduces key sites such as Kafze and Misria, and combs the real timeline of modern people coming out of Africa.
The Evolution of Modern ManMarch 12, 2026770000 to 550000 years ago, the ancestors of modern humans diverged from those of Neanderthals and Denisovans, but there was no complete "reproductive isolation" between the three subspecies ". In fact, from a genetic point of view, they are just a "weaker" ancestor of modern people tens of thousands of years ago. Every modern person has more or less their genes in his body.
The first human out of AfricaFebruary 26, 2026The ancient fossils unearthed from various places can prove that the expansion of the genus of Man began as early as 2 million years ago. At the latest, 1.8 million years ago, the first time that the man's subordinate, the erectus, came out of Africa. It can be said that this is one of the largest geological and historical events in the history of the earth.
GenusMarch 12, 2026"Human" is only a term in the traditional sense, and from a genealogical point of view, it is very imprecise. In a narrow sense, human beings refer to all the people who have existed in history so far. However, human beings in biological taxonomy refer to "human genus", or "true genus". There are 17 known species, and modern people are only one of them.
The Birth of MankindFebruary 26, 2026Human beings used to think that they were very "advanced" and different, a special existence created by "gods" according to their own image or preferences, but since the era when Darwin published the Origin of species, people's traditional cognition of the origin of life has been subverted. Now we know that the history of mankind is not long, only about 7 million years.
The establishment of the Roman RepublicMarch 7, 2026In 509 BC, Rome bid farewell to the royal government and opened a republic. An in-depth analysis of Polybius's theory of "mixed polity" and Monson's "peer-to-peer, annual" logic of checks and balances. Learn how Roman citizens, through power design, prevented the re-birth of the despotic monarchy.

Led by King Leonidas, a force of several thousand Greek allies held the narrow pass against overwhelming odds, delaying the Persian army and buying crucial time for the Greek coalition to regroup and ultimately turn the tide.
