What comes first mutation or natural selection?
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
Can natural selection be observed directly in nature?
Yes, natural selection can be observed directly in nature through examples such as changes in beak size of Galapagos finches in response to food availability or bacteria developing resistance to antibiotics due to overuse. These observations provide evidence of how specific traits can become more or less common in a population over time based on their impact on survival and reproduction.
Which is more likely to be true natural selection or evolution?
Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.
How does natural selection predict a gradualistic mode of evolution?
Natural selection predicts a gradualistic mode of evolution because it involves the gradual accumulation of advantageous traits in a population over time. Individuals with advantageous traits are more likely to survive and reproduce, leading to these traits becoming more common in subsequent generations. This gradual process of selection and accumulation of traits results in the slow and steady change observed in species over time.
How did the theory of natural selection become apparent?
The theory of natural selection became apparent through the work of Charles Darwin, who proposed it in his book "On the Origin of Species" in 1859. Darwin observed that within a population, individuals with advantageous traits are more likely to survive and reproduce, leading to the gradual accumulation of those traits in the population over time. This process of natural selection became a powerful explanation for the diversity of life on Earth.

The molecular and structural similarities observed among these organisms is best explained by which of the following?
natural selection
How does the process of natural selection account for the diversity of the organisms that Darwin observed on the Galapagos islands?
peanut brittle
What is the name for the process in which the organisms best adapted to their environment survive?
Its NaTuRaL sElEcTiOn if you didn't know.
What scientist first described the processes of natural selection as a mechanism for evolution?
Both Charles Darwin and Alfred Russel Wallace independently discovered natural selection.
What were the first Betta fish colors before natural selection?
Brown
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
Can natural selection be observed directly in nature?
Yes, natural selection can be observed directly in nature through examples such as changes in beak size of Galapagos finches in response to food availability or bacteria developing resistance to antibiotics due to overuse. These observations provide evidence of how specific traits can become more or less common in a population over time based on their impact on survival and reproduction.
On the galapagos islands Charles Darwin observed?
On the Galapagos Islands, Charles Darwin observed unique species of birds, tortoises, finches, and marine iguanas. These observations contributed to the development of his theory of evolution by natural selection.
What is the prefix and suffix of natural selection?
The prefix of natural selection is "natural" and the suffix is "-tion".
What famous concept did Darwin name for the first time?
Evolution or natural selection.
What theory did Darwin first introduce in his book?
that evolution happens by natural selection
