LTE (Long Term Evolution) Definition Updated August 22, 2017. Long Term Evolution is a wireless broadband technology designed to support roaming internet access by cell phones and handheld devices. Because LTE offers significant improvements over older cellular communication standards, some refer to it as a 4G technology, along with WiMax.

History of evolutionary thought Evolutionary thought, the conception that species change over time, has roots in antiquity-in the ideas of the ancient Greeks, Romans, and Chinese as well as in medieval Islamic science.

evolution evolutionism. a principle or theory of evolution. — evolutionist, n., adj. Lamarckism. the theory of organic evolution advanced by the French naturalist Lamarck that characteristics acquired by habit, diseases, or adaptations to change in environment may be inherited.

- 1. (Biology) biology a gradual change in the characteristics of a population of animals or plants over successive generations: accounts for the origin of existing species from ancestors unlike them. See also natural selection. 2. a gradual development, esp to a more complex form: the evolution of modern art.

What is Evolution? What is Evolution? QUESTION: What is evolution? ANSWER: Evolution is technically defined as: a gradual process in which something changes into a different and usually more complex or better form. As it is most famously used, evolution is the process by which an organism becomes more sophisticated over time and in response to its environment. The Theory of Evolution is currently the most popular concept of how life reached its current state. Evolution as a biological mechanism is driven by natural selection.

An Introduction to Evolution Evolution is change over time. Under this broad definition, evolution can refer to a variety of changes that occur over time—the uplifting of mountains, the wandering of riverbeds, or the creation of new species.

- Because evolution demands slow change over long periods of time. [65 million years ago is a relatively short period of time geologically speaking, and in the evolutionary concept of timing as well.] But here the fossil record show QUICK change in an obviously SHORT period of time.

What is Evolution? Evolution is a change in the gene pool of a population over time; it can occur due to several factors. Three mechanisms add new alleles to the gene pool: mutation, recombination and gene flow. Two mechanisms remove alleles, genetic drift and natural selection. Drift removes alleles randomly from the gene pool.

Evolution Evolution is a scientific theory used by biologists. It explains how living things change over a long time, and how they have come to be the way they are. The Earth has been around for a very long time. By doing research on the layers of rock, we can find out about its past.

- In this section, we define evolution as it is understood to modern biology and as it applies to ecology. Evolution is defined as the change in the inherited traits of a population of organisms through successive generations.When living organisms reproduce, they pass on to their progeny a collection of traits.ature Education Knowledge 3(10) :6. Evolution describes changes in inherited traits of populations through successive generations. To fully understand the science of ecology, one must first be able to grasp evolutionary concepts.

Divergent evolution Divergent evolution is the accumulation of differences between groups, leading to the formation of new species. The term can also be applied in molecular evolution, such as to proteins that derive from homologous genes.

- Evolution is the gradual genetic change of living organisms over time due to ecological pressures they experience. Individuals in an interbreeding population share in a common gene pool. A population’s gene pool evolves, not an individual, due to changes occurring in such a gene pool. Evolution can occur in several different ways: (1) gene frequencies may be changed by migration, gene flow from another population.

The modern genetic definition of biological evolution is? The modern genetic definition of biological evolution is A. change from one species to another by the natural selection of individual variation B. mutation causes variation and variation is selected for by the environment C. survival of the fittest D. a change in allele frequencies...iological evolution is defined as the change in allele frequencies (where alleles are versions of the same gene that differ in their base sequence) within populations (Freeman and Heron, 2004) http://www.calstatela.edu/faculty/pnargu...

Introduction to evolution Introduction to evolution. Evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms' observable traits. Genetic changes include mutations, which are caused by damage or replication errors in organisms' DNA. As the genetic variation of a population drifts randomly over generations, natural selection gradually leads traits to become more or less com

Human evolution The process of evolution. The process of evolution involves a series of natural changes that cause species (populations of different organisms) to arise, adapt to the environment, and become extinct. All species or organisms have originated through the process of biological evolution. In animals that reproduce sexually, including humans, the term species refers to a group whose adult members regularly interbreed, resulting in fertile offspring -- that is, offspring themselves capable of reproducing.

Unilineal evolution Unilineal evolution (also referred to as classical social evolution(ism)) is a 19th century social theory about the evolution of societies and cultures.ntellectual Thought Edit. Theories of social and cultural evolution are common in modern European thought. Prior to the 18th century, Europeans predominantly believed that societies on Earth were in a state of decline.

Evolution Evolution is a scientific theory used by biologists. It explains how living things change over a long time, and how they have come to be the way they are. Earth is very old. By studying the layers of rock that make up Earth's crust, we can find out about its past. This kind of research is called historical geology.

Linear versus branching evolution Linear versus branching evolution. In the last post I pointed out that probably the most important problem with the word evolution is that it has two distinct meanings in biology. Transformational evolution refers to a linear set of changes in a single object, whereas variational evolution refers to a branching sequence created by unequal survival among a group of objects.
