archaeology: (also archeology) The study of human history and prehistory through the excavation of sites and the analysis of artifacts and other physical remains. Those remains can range from housing materials and cooking vessels to clothing and footprints. People who work in this field are known as archaeologists.
behavior: The way something (often a person or other organism) conducts itself or acts towards others.
bioarchaeologist: Someone who studies human history through research on the remains of ancient people or of the animals closely associated with them.
colleague: Someone who works with another; a co-worker or team member.
connective tissue: Certain groups of cells that attach to form the boundaries for — and interfaces between — many structures throughout the body.
development: (in biology) The growth of an organism from conception through adulthood, often undergoing changes in chemistry, size and sometimes even shape.
DNA: (short for deoxyribonucleic acid) A long, double-stranded and spiral-shaped molecule inside most living cells that carries genetic instructions. It is built on a backbone of phosphorus, oxygen, and carbon atoms. In all living things, from plants and animals to microbes, these instructions tell cells which molecules to make.
force: Some outside influence that can change the motion of an object, hold objects close to one another, or produce motion or stress in a stationary object.
mummy: A body preserved by natural processes or human technology, with some skin and organs remaining.
muscle: A type of tissue used to produce movement by contracting its cells, known as muscle fibers. Muscle is rich in protein, which is why predatory species seek prey containing lots of this tissue.
pharaoh: A term for an ancient Egyptian king, beginning around 1539 B.C. The term had originally meant the royal palace. Later, it came to describe the Egyptian king in that palace, although it was never that king’s formal title or name.
sedentary: Not physically active; an adjective for activities done largely while sitting.
sex: An animal’s biological status with respect to reproductive functions, typically male or female. There are a number of indicators of biological sex, including sex chromosomes, gonads, internal reproductive organs, and external genitals. It can also be a term for some system of mating between male and female animals such that each parent organism contributes genes to the potential offspring, usually through the fertilization of an egg cell by a sperm cell.
tissue: Made of cells, it is any of the distinct types of materials that make up animals, plants or fungi. Cells within a tissue work as a unit to perform a particular function in living organisms. Different organs of the human body, for instance, often are made from many different types of tissues.
trauma: (in medicine) An injury, often a fairly severe one. This term also can refer to a severely disturbing incident (such as a car accident) or memory (such as the death of a loved one).
X-ray: A type of radiation analogous to gamma rays, but having somewhat lower energy.
