InterglacialAn interglacial period (or alternatively interglacial, interglaciation) is a geological interval of warmer global average temperature lasting thousands of years that separates consecutive glacial periods within an ice age. The current Holocene interglacial began at the end of the Pleistocene, about 11,700 years ago.
Penultimate Glacial PeriodThe Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. The penultimate glacial period is officially unnamed just like the Last Glacial Period. The PGP lasted from ~194,000 years ago at the end of the Marine Isotope Stage 7 (MIS 7) interglacial, to ~135,000 years ago, and was succeeded by the Last Interglacial. The PGP approximately coincides with Marine Isotope Stage 6 (MIS 6).
Marine Isotope Stage 5Marine Isotope Stage 5 or MIS 5 is a marine isotope stage in the geologic temperature record, between 130,000 and 80,000 years ago. Sub-stage MIS 5e corresponds to the Last Interglacial, also called the Eemian (in Europe) or Sangamonian (in North America), the last major interglacial period before the Holocene, which extends to the present day.
Last Glacial PeriodThe Last Glacial Period (LGP), also known as the last glacial cycle, occurred from the end of the Last Interglacial to the beginning of the Holocene, from around 115,000–11,700 years ago, and thus corresponds to most of the timespan of the Late Pleistocene. It thus formed the most recent period of what is colloquially known as the "Ice Age".
SangamonianThe Sangamonian Stage (or Sangamon interglacial) is the term used in North America to designate the Last Interglacial (130,000-115,000 years ago) and depending on definition, part of the early Last Glacial Period, corresponding to Marine Isotope Stage 5 (~130-80,000 years ago). While often historically considered equivalent in scope to MIS 5, it is now often used in a more narrow sense to refer to the Last Interglacial only (corresponding to MIS 5e and the European Eemian).

AlpsMajor mountain range in Central EuropeThe Alps () are some of the highest and most extensive mountain ranges in Europe, stretching approximately 1,200 km (750 mi) across several Alpine countries (from west to east): Monaco, France, Switzerland, Italy, Liechtenstein, Germany, Austria, and Slovenia. The Alpine arch extends from Nice on the western to Trieste on the Adriatic and Vienna at the beginning of the Pannonian Basin.
ChileChile, officially the Republic of Chile, is a country in the Southern Cone of southwestern South America. It is the southernmost country in the world and the closest to Antarctica, extending along a narrow strip of land between the Andes Mountains and the Pacific Ocean. According to the 2024 census, Chile had an enumerated population of 18.5 million.
West AsiaWest Asia (also called Western Asia or Southwest Asia) is the westernmost region of Asia. As defined by most academics, UN bodies and other institutions, the subregion consists of Anatolia, the Arabian Peninsula, Iran, Mesopotamia, the Armenian highlands, the Levant, the Sinai Peninsula and the South Caucasus.
Middle PaleolithicThe Middle Paleolithic (or Middle Palaeolithic) is the second subdivision of the Paleolithic or Old Stone Age as it is understood in Europe, Africa and Asia. The term Middle Stone Age is used as an equivalent or a synonym for the Middle Paleolithic in African archeology. The Middle Paleolithic broadly spanned from 300,000 to 50,000 years ago. There are considerable dating differences between regions.
Early modern humanOld Stone Age Homo sapiensReconstruction of early Homo sapiens from Jebel Irhoud, Morocco, c. 315,000 years BPEarly modern human, or anatomically modern human, are terms used to distinguish Homo sapiens (the only extant Hominina species) that are anatomically consistent with the range of phenotypes seen in contemporary humans, from extinct archaic human species.
Skhul and Qafzeh homininsThe Skhul and Qafzeh hominins or Qafzeh–Skhul early modern humans are hominin fossils discovered in Es-Skhul and Qafzeh caves in Israel. They are today classified as Homo sapiens, among the earliest of their species in Eurasia. Skhul Cave is on the slopes of Mount Carmel; Qafzeh Cave is a rockshelter near Nazareth in Lower Galilee.
