The Gila Wilderness is located in southwest New Mexico, north of Silver City and east of Reserve. It contains the West Fork, Middle Fork and much of the East Fork of the Gila River; riverside elevations of around 4,850 feet (1,480 m) are the lowest in the wilderness. The Mogollon Mountains traverse an arc across the wilderness.
The evolution of fish began about 530 million years ago during the Cambrian explosion. It was during this time that the early chordates developed the skull and the vertebral column, leading to the first craniates and vertebrates. The first fish lineages belong to the Agnatha, or jawless fish. Early examples include Haikouichthys.
Pinyon–juniper woodland, also spelled piñon–juniper woodland, is a biome found mid-elevations in arid regions of the Western United States, characterized by being an open forest dominated by low, bushy, evergreen junipers, pinyon pines, and their associates. [1][2] At lower elevations, junipers often predominate and trees are spaced widely ...
Most of these plants have true roots and leaves, and many were quite tall. The tree-like Archaeopteris, ancestral to the gymnosperms, and the giant cladoxylopsid trees had true wood. These are the oldest known trees of the world's first forests. Prototaxites was the fruiting body of an enormous fungus that stood more than 8 meters tall. By the ...

Flowers grow in panicles. Joshua trees grow quickly for a desert species; new seedlings may grow at an average rate of 7.6 cm (3.0 in) per year in their first 10 years, then only about 3.8 cm (1.5 in) per year. [27] The trunk consists of thousands of small fibers and lacks annual growth rings, making determining the tree's age difficult.
