WebAt present, fossil evidence of land plants dates to the Ordovician Period. The abundance and diversity of plant fossils increase into the Silurian Period, and by the middle Devonian Period, the heterosporous life cycle, which allows for more rapid evolution, had occurred independently in several groups, including lycophytes and the ancestors of seed plants. WebIn more technical terms, evolution is defined as change in the gene pool of a population, measurable as changes in allele frequencies in a population. Suppose there is heritable variation in a population, and the heritable variation makes a difference in the survival and reproduction of individual organisms. If these conditions exist, and they ...
