Evolution
the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
Darwin
Charles Darwin discovered evolution
DNA
The molecule inside cells that contains the genetic information responsible for the development and function of an organism.
Adaptation
a change or the process of change by which an organism or species becomes better suited to its environment.
fitness
the ability to survive to reproductive age, find a mate, and produce offspring
natural selection
the process whereby organisms better adapted to their environment tend to survive and produce more offspring
Artificial Selection
the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.
Homologous Structures
Homologous structures are similar physical features in organisms that share a common ancestor, but the features serve completely different functions
Analogous Structures
analogous structures are features of different species that are similar in function but not necessarily in structure and which do not derive from a common ancestral feature
Vestigial Structures
biological structure that has lost a major ancestral function and is usually drastically reduced in size.
embryos/embryology
a branch of science that is related to the formation, growth, and development of embryo.
cytochrome c
Cytochrome c is a heme protein that is localized in the compartment between the inner and outer mitochondrial membranes where it functions to transfer electrons between complex III and complex IV of the respiratory chain.
Heritability
The proportion of variation in a population trait that can be attributed to inherited genetic factors
Cells
the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body
Tissues
A group or layer of cells that work together to perform a specific function.
Organs
a part of an organism that is typically self-contained and has a specific vital function, such as the heart or liver in human
Organism
an individual living thing that carries on the activities of life by means of organs which have separate functions but are dependent on each other
Population
Population is a group of organisms of one species that interbreed and live in the same place at the same time.
Communities
an interacting group of various species in a common location.
Ecosystems
A system that includes all living organisms in an area as well as its physical environment
Biotic
a living component of an ecosystem;
Abiotic
a non-living part of an ecosystem that shapes its environment
Biosphere
The biosphere is made up of the parts of Earth where life exists.
Migration
the seasonal movement of animals from one habitat to another in search of food, better conditions, or reproductive needs
Mimicry
Mimicry occurs when one species of animal resembles another species that has easily recognizable characteristics
Renewable Energy
Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed
Non-Renewable Energy
Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy.
