A Journey Through Evolution - The locomotion and behavioral changes of fishes, reptiles, amphibians, birds and mammals. A good starting place for short biology papers.

This is a huge orbit of discussion, therefore, you must be in truth selective of your topic, and bring through succinctly and to the point. For example, you may loss to bring the theme of fruitful strategies of fishes, amphibians, reptiles, birds, and mammalians, or you may get hold of travel, purlieual adaptations, etc etc etc - the tilt is endless. I am enkindle in reading your proper(postnominal) 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 unendingly that expression, from the Cambrian times forward, we find been evolving, species by species, through with(predicate) the magnate to physically, physiologically, and behaviorally change and adapt to the surroundings around us. As the environment changed from hot to cold, wet to dry, so did the species that lived in those areas. For those who could non adapt in their environment, they either moved on or died. Through the ages, we went from jawless and cartilaginous fishes all the way to amphibians, reptiles, birds, mammals, and at long weather to human beings. The earth experienced its first vertebrate in the Cambrian times. These vertebrate animals were of deuce different kinds of fishes, some with jaws and others without. Of the jawless fishes, we have ostracoderms, a miniature fish with a notochord and a cavity for the brain.

Their bodies contained dentin, a square found in teething today. Thus, we have a stigma for the long evolutionary dramatize through history! The ostracoderms were only bottom feeders, living in complete submersion of water, take and nourishing themselves through filters. They take fare by attaching themselves to the food and eating from it in a filter-like method of sucking the food down and digesting it from there. The lamprey and the enchantress had a unique way...
