Morphologic Relationships to Environment

GENETICS AND EVOLUTION   Evolution is commonly seen as a complex aggregation of random genetic mutations.   A gene with location of probable mutations – alleles   Convergent evolution would suggest, instead, that similar environmental pressures generate similar solutions. In other words – similar environments select for the same characteristics or traits. One of the […]

Leaf Shape, Size, and Thickness

Leaf morphology describes the shape, size, thickness, width, length and fleshiness of the blade.  We use these different characteristics to tease out clues as to the particular morphology and prevalent environment where the plant evolved. All variations of the basic well considered leaf blade are adaptations to different environments. It is important to recognize and […]
