Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

The main differences between the two species is the presence of 2 spines at PVB of RV, presence of a spine at AB of booth valves and the less distinct blade at the AB of H. siciliiensis n.sp..

M: Bairdia sp. Now, a sedimentary level which is stratigraphically higher than the previous one and referable to the Tropites subbullatus/Anatropites spinosus zones of the Tuvalian substage, has been identified at the western side of the Monte Gambanera, nine kilometres south of Monte Scalpello (Fig. Right lateral view of a complete carapace, PCM O FS70. . Description. The taxon Simeonella brotzenorumSohn (1968) which is characteristic of brackishhypersaline conditions (Gerry et al., 1990; Monostori, 1994) is present but with only 2 carapaces. Twenty kilograms of sediments were collected from each of the two stratigraphic levels. In this basin, therefore, occurs a transitional facies between the Panormide and Trapanese shelf facies, on the one hand, and a deep marine facies of the Neo-Tethys, on the other. Through time, the assemblage became more diversified as recorded by the increasing number of families (8 to 12), genera (14 to 18) and species (23 to 36). They are carnivores. Etymology. Evidence for early forms of life comes from fossils. Type species: Mockella muelleriBunza and Kozur (1971); subsequent designation (Kozur, 1973).
