Similar morphological changes resulted in the evolution of the conifer group (pines, larches, cedars and firs). These plants, unlike cycads produce pollen and egg-bearing cones on the same plant individual, however, fertilization and the development of the seed takes longer, but the seeds are equipped with a rich supply of food and a hard, water-proof coat that permits the seed to remain dormant until conditions are right for germination and the establishment of the seedlings. Conifers are successful, even today, with one-third of global forests being composed of them. Both the biggest and most long-lived individual organism in the world are conifers (the redwoods and the bristle-cones respectively).
