Physical anthropology, branch of anthropology concerned with the origin, evolution, and diversity of people. Physical anthropologists work broadly on three major sets of problems: human and nonhuman primate evolution, human variation and its significance (see also race), and the biological bases of human behaviour.
Edward Drinker Cope, an American paleontologist made an observation that an organism evolves over time towards an increased body size in a population lineage which is known as Cope's rule.
The concept of evolution, or the gradual transformation of species over generations, is an integral part of modern biological thought.
Senescence refers to the biological process of aging, characterized by a progressive decline in physiological function and an increased susceptibility to disease and death.
Co-twins, simply referred to as twins, are two offspring produced by the same pregnancy. Twins can be categorized broadly into two types: monozygotic or identical twins, who originate from a single fertilized egg that splits into two, and dizygotic or fraternal twins, who arise from two separate fertilized eggs.
Foster children refer to minors who have been placed in the care of a foster family or foster care system due to various reasons, such as neglect, abuse, or the inability of their biological parents to provide adequate care.
Genomic imprinting refers to an epigenetic phenomenon in which the expression of a gene depends on the parent it's inherited from. Some genes are expressed in a parent-specific manner, meaning they're active only when inherited from the mother or the father.
Genomics, a subfield of genetics, involves the study of the complete set of DNA within a single cell of an organism. The human genome, specifically, contains all of the biological information needed to build and maintain a human being.
The Rh factor derives its name from the Rhesus monkey, in which Landsteiner and Wiener first observed the antigen. However, the Rh factor is present in humans and is independent of the Rhesus monkey's blood group system.
Twins are individuals who are born from the same pregnancy and share the same birth date. They are characterized by a close genetic relationship, as they typically originate from the fertilization of a single egg by a single sperm, which then splits into two embryos.
A Genetic disorder is like a typo in the instructions that tell your body how to grow, develop, and work. You know how a recipe has steps to tell you how to make a cake? Well, our bodies have something like that too. It's called our DNA.
Serogenetics is a term coined to describe the interdisciplinary study of serotonin, a neurotransmitter, and genetics.
Genetic engineering, also known as genetic modification or manipulation, refers to the deliberate modification of an organism's genetic material using biotechnological techniques. It is a relatively young field, having first come into prominence in the latter half of the 20th century.
