Scientific Classification:
     Kingdom: Plantae
          Order: Solanales
               Family: Solanaceae
                    Genus: Datura
                         Species: D. stramonium
Binomial Name: Datura stramonium

     The  Jimson weed (D. stramonium), a foul-smelling, erect, freely-branching herb of the family Solanaceae, is believed to have originated from the Americas. This angiosperm has been used for centuries in relieving the symptoms of asthma and as an analgesic during surgery. It possesses long, thick, fibrous white roots, stout, erect, smooth stems and long, toothed, irregularly undulate leaves. The Jimson weed (D. stramonium) is a basic plant growing in the wilds of various parts of the United States. The roots, stems and leaves of this plant contain trace amounts of natural poisons as well as several alkaloid compounds. Its most toxic part is found in the seed pod that is about the size of a walnut and covered with prickly thorns. According to Joseph Alden, this plant defies evolution in that it possesses thorns that serve no practical purpose in its growth at any stage of its life cycle.

Scientific Classification:
     Kingdom: Plantae
          Order: Fabales
               Family: Fabaceae
                    Genus: Gleditsia
                         Species: G. triacanthos
Binomial Name: Gleditsia triacanthos

      The honey locust tree (G. triacanthos), otherwise known as the thorny locust tree, is a deciduous tree native to central North America. This fast-growing plant can reach a height of about twenty to thirty meters. It has a typical life span of one hundred twenty years although some can live up to one hundred fifty years. The honey locust tree (G. triacanthos) possesses compound leaves that are bipinnate when the tree is young and pinnate when the tree is old. According to Joseph Alden, this plant is often promoted by evolutionists as an organism that has evolved in order to adapt to its surroundings. It is claimed that the tree coevolved with the mastodon. As a means of self-defense, the honey locust tree (G. triacanthos) developed large thorns that are about several inches in length and are attached along its trunk. However, Alden questioned such explanations with the following concepts: How did the honey locust tree (G. triacanthas) develop its own defense mechanism especially considering that mutations occur randomly in nature? The context of coevolution itself contradicts the notion underlying the randomness of mutations. Moreover, why did the other trees ravaged by the mastodon not grow large thorns on their trunks for protection?

Horsetail (E. arvense)

Scientific Classification:
     Kingdom: Plantae
          Division: Pteridophyta
               Class: Equisetopsida
                    Order: Equisetales
                         Family: Equisetaceae
                              Genus: Equisetum
                                   Species: E. arvense
Binomial Name: Equisetum arvense

     The horsetail (E. arvense), otherwise known as snake grass or puzzlegrass, is the only living genus in the Equisetaceae family, a group of vascular plants whose reproduction is via spores rather than by seeds. This plant is an herbal remedy used in ancient Roman and Greek medicine primarily to stop bleeding, heal ulcers and wounds, and treat tuberculosis and kidney problems. Horsetail (E. arvense) contains silicon and for this reason, it is sometimes suggested in the treatment of osteoporosis. According to Alexander Williams, Lynn Margulis noted that although the horsetail (E. arvense) has an excellent fossil record, it does not have any known ancestral group!

Scientific Classification:
     Kingdom: Plantae
          Division: Ginkgophyta
               Class: Ginkgoopsida
                    Order: Ginkgoales
                         Family: Ginkgoaceae
                              Genus: Ginkgo
                                   Species: G. biloba
Binomial Name: Ginkgo biloba

      The Ginkgo tree (G. biloba), a large tree normally twenty to thirty-five meters in height, with some reaching fifty meters, is a unique tree species with no close living relatives and is native to China. It has been used traditionally in medicine and also as a food source. This relatively shade-intolerant species grows best in well-watered and well-drained environments and shows a preference for growth in disturbed sites. According to Alexander Williams, this tree is the only living species of the genus Ginkgo, family Ginkgoaceae, order Ginkgoales, class Ginkgoopsida. Its fossil history extends down to the Permian rocks. Yet, they seem to appear suddenly in the fossil records, fully formed, leaving no clue as to their origin or evolutionary stages.

California Redwood (S. sempervirens)

Scientific Classification:
     Kingdom: Plantae
          Division: Pinophyta
               Class: Pinopsida
                    Order: Pinales
                         Family: Cupressaceae
                              Subfamily: Sequoioideae
                                   Genus: Sequoia
                                        Species: S. sempervirens
Binomial Name: Sequoia sempervirens

      The California redwood (S. sempervirens), otherwise known as the coast redwood or giant redwood, is an evergreen, long-lived monoecious tree that is capable of surviving for up to one thousand eight hundred years. This species includes the tallest known trees in the planet even reaching heights of up to three hundred seventy nine feet. According to Lynn Margulis, conifers which include the California redwood (S. sempervirens), are likely to have descended from the progymnosperms. The problem here is that the progymnosperms are considered to be imaginary evolutionary ancestors; no evidence is present to prove that they have even existed. Moreover, the conifers also gave rise to no other plant phyla. Currently, there is no evidence of them having evolved!
