Ecomorphs as evolutionary definitions?

Question

There have been demonstrations of ecomorphs in different taxa, where each morphology type is associated to a single environment. I know that it happens because special morphological characters increase the fitness and therefore will be positive selected. My question is; if we find similar places (talking about natural pressures and climatic conditions) on earth and given enough time, can we expect to see more or less the same ecomorphs living in different places? Also, assuming that, could evolution be a regarded a non-stochastic process?

Answer 1

The presence or absence of ecomorphs across biomes is not enough evidence to overrule the genetic component of evolution. Most scientists regard evolution as stochastic in the sense that random genetic modifications (whether it be through gene mutation or phenotype expression) have the potential to supply unanticipated advantages to the orgasms that possess and pass them on. One can imagine multiple morphological variants to overcome a single challenge. In some cases, one morphology is more ideal than the others. In this scenario, we may expect convergent evolution to occur, and thus, the presence of ecomorphs. In an alternate scenario, opposing morphotypes may be advantageous, in which case, organisms will appear extremely different from one another (not as ecomorphs).
