5. Genetics
- study of genes and heredity
- has five subcategories: •Molecular Biology – study of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) •Physiology – study of the life processes of organisms •Cytology – study of the function of cells •Histology – study of plant and animal tissues •Biochemistry – study of the molecules within the cell

6. Evolutionary Biology
-study of the change in organisms over time

    Through fossil records from Hyracotherium to Mesohippus to Merychippus to Pleshippus to the Equus, one can see the development of dentition, limbs and skull based on the environment that the horses adapted to with time. Environmental changes from the Eocene to the Holocene brought about natural selection as the horses’ initial characteristics could not adapt. In order to survive, horses evolved traits such as stronger limbs, tougher teeth and others that best fit and adapted to their surroundings. In this lab, we examined these five horse evolution fossils to understand the change in equine morphology in relation to the habitat and the natural selection within the horse population.…

Scientist creates scientific theories from hypothesis that have been corroborated through the scientific method, then gather evidence to test their accuracy. The strength of a scientific theory is related to the diversity of phenomena it can explain, which is measured by its ability to make falsifiable predictions with respect to the phenomena. Scientific theories are the most reliable, rigorous, and comprehensive for of scientific knowledge.…
