Forensic Anthropology : UNIT-2TOPIC : INTRO TO G & D
Introductory Context - FORENSIC SCIENCE
• The word forensic comes from the Latin term forēnsis, meaning "of or before the forum."[3] The history of the term originates from Roman times, during which a criminal charge meant presenting the case before a group of public individuals in the forum.
• Both the person accused of the crime and the accuser would give speeches based on their sides of the story. The case would be decided in favor of the individual with the best argument and delivery.
• This origin is the source of the two modern usages of the word forensic – as a form of legal evidence and as a category of public presentation.
Forensic science’s Common Definition
• Forensic science is the application of science to criminal and civil laws.
• Forensic scientists collect, preserve, and analyse scientific evidence during the course of an investigation.
• While some forensic scientists travel to the scene to collect the evidence themselves, others occupy a purely laboratory role, performing analysis on objects brought to them by other individuals. [1]
• In addition to their laboratory role, forensic scientists testify as expert witnesses in both criminal and civil cases and can work for either the prosecution or the defense.
CHARACTERISTICS OF LIVING THINGS/ORGANISMS
• FEED & USE ENERGY TO• GROW & DEVELOP• MOVE• RESPOND• REPRODUCE• ORGANIZATION OF CHEMICALS IN CELLS• CATABOLIZE & REMOVE WASTE
HUMAN GROWTH
• The increase in size of a living being or any of its parts occurring WITH THE PASSAGE OF TIME.• A normal process of increase in size of an organism as a result of proliferation of cells or enlargement of cells/tissues , similar to that originally present.An abnormal formation, such as a tumor.
HUMAN GROWTH(Contd.)
• A normal process of increase in size of an organism as a result of accretion of tissue (the process of growth or increase, typically by the gradual accumulation of additional layers or matter).• The proliferation (Rapid increase in the
number of cells or enlargement of cells).
DEVELOPMENT
• Development is both growth and differentiation.
• Unlike Growth, development results in differentiation of cells to tissues, organs, systems by changing cell structure, composition, shapes, colors and chemical bonds etc.
Development (contd.)• BUILDING ENHANCEMENT OR DEVELOPMENT MAY BE PHYSICAL,
COGNITIVE, AFFECTIVE, SPIRITUAL, EDUCATIONAL, SOCIAL, ENVIRONMENTAL ETC. FOR DEVELOPING SELF-HELP OR SOCIAL HELP MECHANISMS.
• Physical development is responsible for structural body differentiation and maturity in sizes, shapes, composition.
• cognitive development is the development of• intelligence, conscious thought, and problem-solving ability.• And so on for other categories of development which will be dealt
later while dealing with respective topics as per coverage in the syllabus.
Growth vs Development Since, growth and development are two words in the English language that have the same connotation (the associated or secondary meaning of a word or expression in addition to its explicit or primary meaning: A possible connotation of “home” is “a place of warmth, comfort, and affection).
It is useful to know the difference between growth and development so that they can be used correctly in the right context. Growth is a process of becoming larger or longer or more numerous or more important, mostly a physical change;Development is a process in which something transforms (mostly positive) into a different stage or improves in structure & function, it may be physical, social or psychological.
