What did Darwin propose by saying that over a long natural selection could lead to?
Darwin proposed that over a long time, natural selection could lead to the gradual change and divergence of species from a common ancestor, resulting in the formation of new species through the process of adaptation to their environment.
What do organisms change into over long periods of time?
Organisms can evolve into new species over long periods of time through the process of natural selection and adaptation to their environment. This can result in the development of new characteristics and the divergence of populations into separate species.
What gradual change in living things over long periods of time called?
The gradual change in living things over long periods of time is called evolution. It involves genetic variation, natural selection, and adaptation leading to the development of new species.
How does the theory of punctuated equilibrium differ from natural selection?
They describe different things, so they cannot really be compared. Natural selection is the mechanism that gives direction to evolution. Punctuated equilibria is a model for the varying rates of adaptation caused by natural selection.

How do variation and natural selection work together to cause evolution?
They help each other by gradually accumulate in a species, while unfavorable ones may disappear. Over a long time, natural selection can lead to changes.
What gradual change in living things over long periods of time called?
The gradual change in living things over long periods of time is called evolution. It involves genetic variation, natural selection, and adaptation leading to the development of new species.
The gradual change in living things over long periods of time is called?
The gradual change in the characteristics of a species over time is called evolution. The theory of evolution by natural selection was first proposed by Charles Darwin.
What are long periods of unusually low precipitation?
Long periods of unusually low precipitation are called droughts. Droughts can have significant impacts on agriculture, water supply, and natural ecosystems. They can lead to crop failures, water shortages, and ecosystem degradation.
How does the theory of punctuated equilibrium differ from natural selection?
They describe different things, so they cannot really be compared. Natural selection is the mechanism that gives direction to evolution. Punctuated equilibria is a model for the varying rates of adaptation caused by natural selection.
What are Darwin's four theories of evolution?
Species can adapt to their environment over long periods of time.Over a very long period of time, the traits of a species can change.Species change over long periods of time according to natural selection.
Is it possible for evolution to occur by both natural selection and punctuated equilibrium?
Yes. Evolution via punctuated equilibrium still depends on natural selection. In punctuated equilibrium there are long periods in which most species are well-suited to their environments, and so there is is little selective pressure to change. These periods are punctuated by times of more rapid environmental change and greater stress, which results in greater selective pressure for populations to change.
Is artificial selection or natural selection benefit an environment more?
Natural selection generally benefits the environment more than artificial selection because it promotes the survival of species that are best adapted to their ecosystems, leading to biodiversity and ecological balance. In contrast, artificial selection often prioritizes traits desirable to humans, which can result in reduced genetic diversity and potential vulnerability to diseases or environmental changes. While both processes can lead to adaptations, natural selection fosters resilience and stability in ecosystems. Ultimately, the benefits of natural selection are broader and more sustainable in the long term.
Large scale evolutionary trends are the result of?
macroevolution .........novanet
What resulted from a genetic variation that was favored by natural selection?
The genetic variation that was favored by natural selection led to the increased frequency of the advantageous trait in a population over time, resulting in adaptation to the environment. This can lead to improved survival and reproductive success for individuals carrying the advantageous variation.
