Physiological Evidences of Evolution

Physiological Evidences of Evolution EVOLUTION-PHYSIOLOGICAL EVIDENCES Study of the functional aspects of the organism is called physiology The organs and organ systems are similar in the closely related animals The functional aspect of closely related animals is also same The physiological evidences are studied in three headings They are 1 FUNDAMENTAL UNITY OF LIFE

Analogy vs Homology

Analogy or analogous structures is actually the one that does not indicate there is a recent common ancestor between two organisms Even though the anatomical structures being studied look similar and maybe even perform the same functions they are actually a product of convergent evolution Just because they look and act alike does not mean they are related closely on the tree of life

Cancer Is to Embryology as Mutation Is to Genetics

Despite numerous advances in cell biology genetics and developmental biology cancer origin has been attributed to genetic mechanisms primarily involving mutations Embryologists have expressed timidly cancer embryological origin with little success in leveraging the discussion that cancer could involve a set of conventional cellular processes used to build the embryo during morphogenesis

Morphological characteristics of cultured olfactory bulb

Morphological characteristics of cultured olfactory bulb cells Fracek S Guo This is similar to normal embryological development where expression of tyrosine hydroxylase activity in the intact olfactory bulb occurs after the olfactory nerve reaches the bulb (McLean and Shipley 1988) Although the cell types seen in culture parallel the cell types seen in the intact brain the degree to

Features Used to Classify Animals – Biology

Animals are primarily classified according to morphological and developmental characteristics such as a body plan One of the most prominent features of the body plan of true animals is that they are morphologically symmetrical This means that their distribution of body parts is balanced along an axis Additional characteristics include the number of tissue layers formed during development

27 1A: Characteristics of the Animal Kingdom

Even though members of the animal kingdom are incredibly diverse most animals share certain features that distinguish them from organisms in other kingdoms All animals are eukaryotic multicellular organisms and almost all animals have a complex tissue structure with differentiated and specialized tissues Most animals are motile at least during certain life stages All animals require a

morphology

Morphology continues to be of importance in taxonomy because morphological features characteristic of a particular species are used to identify it As biologists have begun to devote more attention to ecology the identification of plant and animal species present in an area and perhaps changing in numbers in response to environmental changes has become increasingly significant
