Plains zebras are adapted for grazing on both long, tough grass stems and newly emerging short grass. In some areas, it rarely feeds below 100–150 mm (3.9–5.9 in) to ground level. It ranges more widely than many other species, even into woodlands , and it is often the first grazing species to appear in a well-vegetated area.
The word zebra was traditionally pronounced with a long initial vowel, but over the course of the 20th century the pronunciation with the short initial vowel became the norm in British English. [7] The pronunciation with a long initial vowel remains standard in American English. [8]
There is a positive relationship between mass at birth and length of gestation in eutherian mammals. [17] Larger mammals are more likely to produce a well-developed neonate than small mammals.
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.

500 million years of climate change Ice core data for the past 400,000 years, with the present at right. Note length of glacial cycles averages ~100,000 years. Blue curve is temperature, green curve is CO 2, and red curve is windblown glacial dust (loess). Scale: Millions of years before present, earlier dates approximate.
