Populations evolve. Because individuals in a population vary, some in the population are better able to survive and reproduce given a particular set of environmental conditions. These individuals generally survive and produce more offspring, thus passing their advantageous traits on to the next generation.

Why would a species evolve adaptations?
In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. ... This enables better survival and reproduction compared with other members of the species, leading to evolution.
What causes a species to evolve or diversify?
Evolution and diversity result from the interactions between organisms and their environments and the consequences of these interactions over long periods of time. Organisms continually adapt to their environments, and the diversity of environments that exists promotes a diversity of organisms adapted to them.
Why do some species evolve while others go extinct?
When conditions change, some species possess adaptations that allow them to survive and reproduce, while others do not. ... If the environment changes slowly enough, species will sometimes evolve the necessary adaptations, over many generations.
Why is evolution important?
Understanding evolution helps us solve biological problems that impact our lives. ... To control hereditary diseases in people, researchers study the evolutionary histories of the disease-causing genes. In these ways, a knowledge of evolution can improve the quality of human life.
What is the main cause of evolution?
Three main mechanisms cause allele frequency change: natural selection, genetic drift, and gene flow. Macroevolution, on the other hand, refers to change at or above the level of the species. Advances in technology have given us tools that have dramatically advanced our understanding of how evolution occurs.
What is known about evolution?
In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. ... Evolution relies on there being genetic variation? in a population which affects the physical characteristics (phenotype) of an organism.
How do new species evolve?
Biologists believe that new species evolve from existing species by a process called natural selection. ... Organisms that inherit that favorable new gene are likely to become more abundant than others of the species. Sometimes the population of a species becomes separated into two areas, by geography or by climate.
Why do species evolve and survive?
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Why is extinction important to evolution?
Extinction is the dying out of a species. Extinction plays an important role in the evolution of life because it opens up opportunities for new species to emerge.
What would happen if there was no evolution?
However, even if the environment has no effect on allelic frequencies chance can make them vary across time. This is also evolution. So a strict no-evolution scenario would mean that a population, generation after generation, will always show the same allelic frequencies (no matter if natural selection exists or not).
Why is evolution essential to life on Earth?
Evolution explains how living things are changing today and how modern living things have descended from ancient life forms that no longer exist on Earth. As living things evolve, they generally become better suited for their environment. This is because they evolve adaptations.
What is an evolutionary advantage?
The evolutionary advantage of consciousness lies in the ability to avoid inflexible behavior patterns (based mostly on genetic learning) that animals follow. ... A population of higher heritability and variability is considered to have an evolutionary advantage over a population of lower heritability and variability.
What are the 5 main causes of evolution?
Five different forces have influenced human evolution: natural selection, random genetic drift, mutation, population mating structure, and culture.
What causes evolution to occur?
There are five key mechanisms that cause a population, a group of interacting organisms of a single species, to exhibit a change in allele frequency from one generation to the next. These are evolution by: mutation, genetic drift, gene flow, non-random mating, and natural selection (previously discussed here).
What are the 4 causes of evolution?
There are four forces of evolution: mutation, gene flow, genetic drift, and natural selection.
