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.
Fecundity, a term rooted in biology, denotes the potential reproductive capacity of an organism or population. Fecundity, a term derived from the Latin word 'fecunditas,' signifies the ability of an organism to produce offspring.
Gerontology is an interdisciplinary field of science that explores the physical, psychological, and socio-cultural aspects of aging. It's a branch of study that's increasingly relevant as the global population continues to age at
Lethal genes are those genetic sequences that can cause the death of an organism, typically before reproductive age, when expressed in a certain manner.
Orthogenesis, also known as Progressive Evolution, is a biological theory that suggests species evolution follows a predetermined path, leading to a specific endpoint.
These so-called 'ecological rules of evolution' have provided a profound insight into how organisms adapt and evolve in response to their environment.
Chromosomal abnormalities occur when there is a significant change in the number or structure of chromosomes in a person's cells. This can include deletions, duplications, inversions, or translocations of chromosome parts.
Polygenes refer to a group of multiple genes that contribute to the expression of a specific trait or characteristic. Unlike single genes that have a clear-cut influence, polygenes work together to influence a trait's variation and complexity.
Genomic Library is a collection of the total genomic DNA from a single organism. The DNA is stored in a population of identical vectors, each containing a different insert of DNA.
Deforestation, the large-scale removal of forests, has become a widespread ecological concern in the past century. Its far-reaching effects on the environment have contributed to an ecological imbalance with both immediate and long-term consequences.
Recombinant DNA technology, also known as genetic engineering, refers to the manipulation and modification of DNA molecules from different sources to create new combinations of genetic material.
While the standard blueprint of human genetic material consists of 46 chromosomes, sometimes, nature deviates from this pattern. These deviations, referred to as chromosomal aberrations or disorders, manifest in two primary forms: numerical and structural aberrations.
Life Tables, often known as mortality tables, play a critical role in demographic analysis. They offer comprehensive snapshots of mortality rates and survival probabilities for a population at different ages, providing the foundation for analyzing patterns and predicting future trends.
