Principles of Evolution
Theory of evolution
-
Natural Selection
Through this process, the best-adapted organisms displace the least adapted through the slow accumulation of favourable genetic changes in the population over generations.
Adaptation
It's the capacity that provides some function or improved characteristic within some species within the same population.
Species
Set of members who have the same physical characteristics and the same genetic code (with variations) and who are also able to reproduce each other in nature.
Evidence of evolution
Embryonic Development
The genes that control the establishment of embryos are highly conserved in all vertebrates and therefore are similar at the beginning.
Biogeography
It's responsable for studying the geographical distribution of animals and plants, as well as the place where they originate, how did they came to occupy their current distribution and when or how did they get there.
Fossil Record
Remains, traces or other indications of organisms that lived in
other geological times.
Vestigial Structures
It refers to organs or parts of degenerate organs that are no longer functional, but that had some important function in the ancestors of the species.
Comparative Anatomy
It allows us to determine the similarities in the anatomy of different species of living beings; the body of individuals belonging to species more or less close to each other respond to a common model.
Molecular Biology
A science that is responsible for the study of the different processes that take place within the cells of living beings but on a molecular scale. It has also made it possible to determine that all species come from a common ancestor.
