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 ...
A significant contribution to English natural history was made by parson-naturalists such as Gilbert White, William Kirby, John George Wood, and John Ray, who wrote about plants, animals, and other aspects of nature. Many of these men wrote about nature to make the natural theology argument for the existence or goodness of God. [23]
Land plants evolved from a group of freshwater green algae, perhaps as early as 850 mya, [3] but algae-like plants might have evolved as early as 1 billion years ago. [2] The closest living relatives of land plants are the charophytes, specifically Charales; if modern Charales are similar to the distant ancestors they share with land plants, this means that the land plants evolved from a ...
People trees, by Pooktre. Tree shaping is the practice of changing living trees and other woody plants into man made shapes for art and useful structures. There are a few different methods [135] of shaping a tree. There is a gradual method and there is an instant method.
Nature is an inherent character or constitution, [1] particularly of the ecosphere or the universe as a whole. In this general sense nature refers to the laws, elements and phenomena of the physical world, including life.
The first translation into English, with an introduction and parallel Greek and English texts, was made by Sir Arthur Hort (1864–1935). It was published simultaneously by William Heinemann in London and G. P. Putnam's Sons in New York, as a two-volume book Theophrastus Enquiry into Plants and minor works on odours and weather signs in 1916. [7]
It may also appear as a cosmic tree or an eagle and serpent tree. [132] [133] Forms of the world tree include the archetypal tree of life, which is in turn connected to the Eurasian concept of the sacred tree. [134] Another widespread ancient motif, found for example in Iran, has a tree of life flanked by a pair of confronted animals. [135]
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
