Creatonism
Elements that allow variability
The belief that the universe and the various forms of life were created by God out of nothing.
Societies evolve gradually; it was created by Jean Baptiste de Lamarck and is the result of two forces combined: acquired characteristics, and the existence of a universal creative principle.
Organic evolution claiming that acquired characteristics are transmitted to offspring; an organism can pass on characteristics that it has acquired through use or disuse.
Theory of the evolutionary mechanism propounded by Charles Darwin as an explanation of organic change. It denotes Darwin’s specific view that evolution is driven mainly by natural selection.
Changes in the earth's crust during geological history have resulted from the action of continuous and uniform processes.
Natural disasters such as floods and volcanic eruptions shaped Earth's landforms and caused extinction of some species.
English natural scientist who formulated a theory of evolution by natural selection (1809-1882); his travesy with the Beagle throughout the world got him to study evolution in animals (hence his book "The Origin of Species")
Evolution
Natural Selection
Adaptation
Species
The process of change in the diversity and adaptations of living things.
It's the capacity that provides some function or improved characteristic within some species within the same population.
Through this process, the best-adapted organisms displace the least adapted through the slow accumulation of favourable genetic changes in the population over generations.
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.
Non-random Mating
Natural Selection
Interactions with Environment
Synthetic Evolution
Genetic Drift
Embryonic Development
Biogeography
Fossil Record
Vestigial Structures
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.
Remains, traces or other indications of organisms that lived in
other geological times.
The genes that control the establishment of embryos are highly conserved in all vertebrates and therefore are similar at the beginning.
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.
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.
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.
A change in the allele frequency of a population as a result of chance events rather than natural selection.
It explains the evolution of life in terms of genetic changes occurring in the populations that leads to the formation of new species. It also explains about the genetic population or mendelian population, gene pool and the gene frequency.
A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.
Mating between individuals of the same phenotype or by those who live nearby.
As part of an ecosystem, each organism interacts continuously with its environment; they can also be defined as the interactions between the human social system and the ecosystem.
