Abstract:
Change and adaptation are the phenomena of life.
Throughout the existence of life on earth, biological systems
have adapted and changed physiologically and morphologically
to acquire a homeostasis most suitable for the demands
of the environment. The genetic composition is interchangeable
among organisms, and the expressions of traits are the
response genes in combination to biological requirements.
Human interventions changed a plethora of gene expressions
by direct selection including hunting, domestication, and
selecting for desirable traits. Human interventions on the biological
world are moving rapidly from direct to indirect interventions
through overutilization of resources and secondary
effects of industrial development on the earth’s ecosystems.
