Darwin's theory of adaptation follows from three postulates and is termed the process of evolution by natural selection. identify these postulates.

The first postulate is that while a population has the capacity to bear an infinite number of offsprings, this is infeasible since the environment/habitat has limited number of resources hence can only support a finite number of the population depending on the resources available. The second postulate indicates that in a population, there exist variations in traits with some more beneficial than other for survival in the environment.  The third postulate states that only the individuals with the superior traits will produce offsprings over generations and preserve their traits in the population.  

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
