The Theory of Evolution does not seek to how life began, although there are several very credible hypotheses for the beginning of life on Earth.
Individual organisms often differ from both of their parents, at least in quite minor ways. People have taken advantage of these changes by selecting the most desirable plant or farm animal to breed from. Thus, over time, new and better varieties are developed. Nature has the same ability to develop new varieties, whenever a chance variation gave the individual an advantage.
Charles Darwin believed that [in nature] a well marked variety can justly be called an incipient species, although the variety, for any number of reasons, may never progress to becoming a distinct species. If a variety were to flourish so as to exceed in numbers the parent species, then it would become the species, and the parent as the variety; or it may come to supplant and exterminate the parent; or both might coexist and both rank as independent species.
The principal driver of evolution is natural selection. Where a variation gave an individual a greater chance of surviving and passing on its genes, then that variation would flourish. Further favourable variations could gradually lead towards development of an entirely new species.
Some species, such as peacocks, can not readily be explained by natural selection. The explanation in this case is sexual selection.

Why did evolutionary theory prove important in taxonomy?
Evolutionary theory provides a framework for understanding the relationships between organisms based on their shared ancestry and descent with modification. This has greatly influenced taxonomy by allowing classifications to reflect the evolutionary history of organisms, leading to more accurate and robust classification systems. By incorporating evolutionary principles, taxonomists can better organize and categorize species based on their evolutionary relationships.
What are all organisms made of according to the cell theory?
cell:)
What is the modern theory of evolution also known as?
The modern theory of evolution is also known as the synthetic theory of evolution or the modern synthesis. It combines Darwin's theory of natural selection with genetics and other fields of biology to explain how organisms evolve over time.
What can two organisms not do according to the biological species concept?
According to the biological species concept, two organisms are of different species if they do not do which of these
What theory proposes species evolve during short periods of rapid change?
Punctuated equilibrium theory proposes that species evolve rapidly during short periods of significant change, followed by long periods of stability with little evolutionary change. This contrasts with gradualism, which suggests that evolution occurs steadily over long periods of time.
When did life begin according to the evolutionary theory?
According to the evolutionary theory, life is believed to have begun around 3.5 to 4 billion years ago with the emergence of simple single-celled organisms such as bacteria. These early life forms eventually evolved and diversified into more complex organisms over millions of years.
What is difference between systematics & taxonomy?
Systematics: 1. Does not change with change in theory. 2. It deals with classification and evolutionary history. It remains same with time . Taxonomy: 1. It changes with change in theory. It deals with classification of oraganisms only,yet not evolutionary history. It doesn't remain same with time.
Define evolutionary theory?
Evolutionary theory is a scientific explanation for the mechanisms and patterns of biological evolution, proposing that species change over time through the process of natural selection, genetic drift, and other factors. It helps to understand how organisms have evolved and diversified over generations.
According to the evolutionary theory what was most likely evolutionary precursor?
hominids
Theory that evolutionary change occurs slowly?
Gradualism.

What best describes evolutionary theory?
Evolutionary theory suggests that living organisms have evolved over time through a process of natural selection, genetic variation, and adaptation to their environment. It explains how species change and diversify over generations, resulting in the biodiversity we see today. Evolutionary theory is supported by a wealth of scientific evidence from multiple disciplines, including genetics, paleontology, and comparative anatomy.
According to the theory of punctuated equilibrium when does stasis occur?
Stasis in the theory of punctuated equilibrium refers to long periods of evolutionary stability without significant change in a species. This stasis occurs between shorter bursts of rapid evolutionary change or speciation events.

What is evolutionary adaptation?
Evolutionary adaptation refers to the process of organisms changing over time in order to remain alive. This evolution is a theory of natural selection.
