This is a huge area of discussion, therefore, you must be in truth selective of your topic, and write succinctly and to the point. For example, you may emergency to bring the theme of reproductive strategies of fishes, amphibians, reptiles, birds, and mammals, or you may cull travel, environmental obligeations, etc etc etc - the list is endless. I am enkindle in reading your specific interest in evolutionary biology. Throughout the millions of historic period of evolutionary progress, the human being, a mammal of great ground came to be. But, it wasnt always that way, from the Cambrian clock forward, we have been evolving, species by species, through with(predicate) the ability to physicall(a)y, physiologically, and behaviorally change and adapt to the environment around us. As the environment changed from hot to cold, roiled to dry, so did the species that lived in those areas. For those who could non adapt in their environment, they either move on or died. Throu gh the ages, we went from jawless and cartilaginous fishes all the way to amphibians, reptiles, birds, mammals, and at long last to human beings. The background experienced its first craniate in the Cambrian times. These vertebrate animals were of two different kinds of fishes, some with jaws and others without. Of the jawless fishes, we have ostracoderms, a small fish with a notochord and a cavity for the brain.
Their bodies contained dentin, a material found in teeth today. Thus, we have a marker for the long evolutionary explode through register! The ostracoderms were simply bottom feeders, living in com plete submergence of water, eating and nour! ishing themselves through filters. They win food by attaching themselves to the food and eating from it in a filter-like method of suck the food down and digesting it from there. The lamprey and the beldame had a laughable way...
