Some life sciences focus on a specific type of organism. For example, zoology is the study of animals, while botany is the study of plants. Other life sciences focus on aspects common to all or many life forms, such as anatomy and genetics. Some focus on the micro scale (e. g. molecular biology, biochemistry) other on larger scales (e. g. cytology, immunology, ethology, ecology). Another major, branch of life sciences involves understanding the mind – neuroscience.
