Human history is the record of humankind from prehistory to the present. Modern humans evolved in Africa around 300,000 years ago and initially lived as hunter-gatherers . They migrated out of Africa during the Last Ice Age and had spread across Earth's continental land except Antarctica by the end of the Ice Age 12,000 years ago.
Human ecology has a history of focusing attention on humans' impact on the biotic world. [ 1 ] [ 34 ] Paul Sears was an early proponent of applying human ecology, addressing topics aimed at the population explosion of humanity, global resource limits, pollution, and published a comprehensive account on human ecology as a discipline in 1954.
Landscape ecologists view noncyclical human events and natural disasters as external influences, while historical ecologists view disturbances as an integral part of the landscape's history. It is this integration of the concept of disturbance and history that allows for landscape to be viewed as palimpsests , representing successive layers of ...
It is the sovereign state with the shortest history of human settlement (followed by Mauritius). [122] East Pacific: Floreana Island: 1805: Black Beach: First settled 1805–1809 by Patrick Watkins.

The Great Acceleration is the dramatic, continuous and roughly simultaneous surge across a large range of measures of human activity, first recorded in the mid-20th century and continuing into the early 21st century.
Until 2013 with the discovery of the 1.4-million-year-old infant tooth from Barranco León, Orce, Spain, these were the oldest human fossils known from Europe, [25] although human activity on the continent stretches back as early as 1.6 million years ago in Eastern Europe and Spain indicated by stone tools.
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
Coral reefs are dying around the world. [146] Human activities have substantial impact on coral reefs, contributing to their worldwide decline. [147] Damaging activities encompass coral mining, pollution (both organic and non-organic), overfishing, blast fishing, as well as the excavation of canals and access points to islands and bays.
