Etymology
The proper derivation of the word ''Yucatán'' is widely debated. 17th-century Franciscan historian
Diego López de Cogolludo offers two theories in particular.
In the first one,
Francisco Hernández de Córdoba, having first arrived to the peninsula in 1517, inquired the name of a certain settlement and the response in
Yucatec Mayan was "I don't understand", which sounded like ''yucatán'' to the Spaniards.
[ There are many possibilities of what the natives could have actually said, among which "''mathan cauyi athán''", "''tectecán''", "''ma'anaatik ka t'ann''" and "''ci u t'ann''".] This origin story was first told by Hernán Cortés
Hernán Cortés de Monroy y Pizarro Altamirano, 1st Marquis of the Valley of Oaxaca (December 1485 – December 2, 1547) was a Spanish ''conquistador'' who led an expedition that caused the fall of the Aztec Empire and brought large portions o ...
in his letters to Charles V.[ Later 16th century historians Motolinia and Francisco López de Gómara also repeat this version.][ In some versions the expedition is not the one captained by Córdoba but instead the one a year later captained by Juan de Grijalva.] The second major theory is that the name is in some way related to the yuca crop, as written by Bernal Díaz del Castillo.[ Others theories claim that it is a derivative of Chontal Tabascan word ''yokat'an'' meaning speaker of the Yoko ochoco language, or an incorrect ]Nahuatl

History
Pre-human
The Yucatán Peninsula is the site of the Chicxulub crater impact, which was created 66 million years ago by an asteroid of about 10 to 15 kilometers (6 to 9 miles) in diameter at the end of the Cretaceous Period.
Prehistory
In 2020, an underwater archaeological expedition led by Jerónimo Avilés excavated Chan Hol cave, near the Tulum archaeological site in the state of Quintana Roo on the peninsula, and revealed the skeleton of a woman approximately 30 years of age who lived at least 9,900 years ago. According to craniometric measurements, the skull is believed to conform to the mesocephalic pattern, like the other three skulls found in Tulum caves. Three different scars on the skull of the woman showed that she was hit with something hard and her skull bones were broken. Her skull also had crater-like deformations and tissue deformities that appeared to be caused by a bacterial relative of syphilis
Syphilis () is a sexually transmitted infection caused by the bacterium ''Treponema pallidum'' subspecies ''pallidum''. The signs and symptoms depend on the stage it presents: primary, secondary, latent syphilis, latent or tertiary. The prim ...
.
According to study lead researcher Wolfgang Stinnesbeck, "It really looks as if this woman had a very hard time and an extremely unhappy end of her life. Obviously, this is speculative, but given the traumas and the pathological deformations on her skull, it appears a likely scenario that she may have been expelled from her group and was killed in the cave, or was left in the cave to die there".
The newly discovered skeleton was 140 meters away from the Chan Hol 2 site. Although archaeologists assumed the divers had found the remains of the missing Chan Hol 2, the analysis soon proved that these assumptions were erroneous. Stinnesbeck compared the new bones to old photographs of Chan Hol 2 and showed that the two skeletons represent different individuals.
Due to their distinctive features, study co-researcher Samuel Rennie suggest the existence of at least two morphologically diverse groups of people living separately in Mexico

landscape. Sinkholes, known locally as cenotes, are widespread in the northern lowlands.
According to the Alvarez hypothesis, the mass extinction of the non-avian dinosaurs at the transition from the Cretaceous to the Paleogene Period, the Cretaceous–Paleogene boundary (K–Pg boundary), 66 million years ago was caused by an asteroid impact somewhere in the greater Caribbean Basin. The deeply buried Chicxulub crater is centered off the north coast of the peninsula near the town of Chicxulub. The now-famous "Ring of Cenotes," a geologic structure composed of sinkholes arranged in a semi-circle, outlines one of the shock-waves from this impact event in the approximately 66-million-year-old rock. The existence of the crater has been supported by evidence including the aforementioned "Ring of Cenotes", as well as the presence of impact debris such as shocked quartz and tektites, a type of glass formed during meteorite impacts.
The Arrowsmith Bank is a submerged bank located off the northeastern end of the peninsula.
Climate
The peninsula has a tropical climate, which ranges from semi-arid in the northwest to humid in the south. Average annual rainfall ranges from less than in the driest parts of the northwest up to in the Petén Basin to the south. Rainfall varies seasonally, with August and September generally the wettest months.

, the peninsula lies within the Atlantic Hurricane Belt, and with its almost uniformly flat terrain it is vulnerable to these large storms coming from the east, and the area has been devastated by many hurricanes, such as Hurricane Gilbert, Hurricane Emily, Hurricane Wilma, and Hurricane Dean.
Strong storms called ''nortes'' can quickly descend on the Yucatán Peninsula any time of year. Although these storms pummel the area with heavy rains and high winds, they tend to be short-lived, clearing after about an hour. The average percentage of days with rain per month ranges from a monthly low of 7% in April to a high of 25% in October. Breezes can have a cooling effect, humidity

The thousands of sinkholes known as cenotes throughout the region provide access to the groundwater system. The cenotes have long been relied on by ancient and contemporary Maya people.
Ecology
The vegetation and plant communities of the peninsula vary from north to south. The Yucatán dry forests occupy the dry northwestern peninsula, and include dry forests and scrublands and cactus scrub. The Yucatán moist forests occur across the middle and east of the peninsula, and are characterized by semi-deciduous forests where 25 to 50% of the trees lose their leaves during the summer dry season. The Belizian pine forests are found in several enclaves across central Belize. The southernmost portion of the peninsula is in the Petén–Veracruz moist forests ecoregion, an evergreen rain forest.

Economy
In the late historic and early modern eras, the Yucatán Peninsula was largely a cattle ranching, logging, chicle and henequen production area. Since the 1970s, the Yucatán Peninsula has reoriented its economy towards tourism, especially in the Mexican state of Quintana Roo. Aside from tourism, another source of income that is important in the Peninsula is logging as well as chicle industries specifically in Belize. Oil was also found in certain parts of the Yucatán, bringing in more economic opportunities. Once a small fishing village, Cancún in the northeast of the peninsula has grown into a thriving city. The Riviera Maya, which stretches along the east coast of the peninsula between Cancún and Tulum, houses over 50,000 beds. The best-known locations are the former fishing town of Playa del Carmen, the ecological parks Xcaret and Xel-Há and the Maya ruins of Tulum and Coba.
Population
The population of the Yucatán Peninsula is very different throughout each part of the Peninsula. Population density and ethnic composition are two factors that play into the total population. The most populated area is Mérida in Yucatán state and the surrounding region, contrasted by the state of Quintana Roo, the least populated part of the peninsula. In terms of ethnic composition, a majority of the population consisted of both Maya and Mestizos.
