If you say you have an island inhabited by a species then something like an earth quak happens and the island splits apart and both parts cant see each other or any thing like that you have the species split onto seperate islands there would be different forms of food on them and they would have to adapt to them or maby different land variations like ones island will have bushes and one will have trees the animal could become a girraf as an example to reach the trees or a cow to reach the bushes.
What else can I help you with?
Is it true that through natural selection harmful variations gradually accumulate in a species?
yes
How do hepful variations accumulate in a specs over time?
Helpful variations accumulate in a species over time through the process of natural selection. Individuals with traits that confer advantages in their environment are more likely to survive, reproduce, and pass those traits to their offspring. Over generations, these beneficial traits become more common within the population, leading to gradual adaptations. Additionally, genetic mutations and recombination contribute to the diversity of traits available for selection.
How does natural variation affect evolution?
Natural selection (the driving force of evolution) is the selection of genetic variations by how they effect the organism's chances of survival or reproduction. If they diminish it's chances, the organism or it's immediate offspring die and the gene is gone. If the genetic variations increase it's chances, then it survives. Without genetic variations there can be no evolution. Natural selection is the selection (by environmental pressures) of those variations.
Natural selection cannot occur without what?
Variations within a population. Variations mean traits that only certain individuals have that give the individual a greater or lesser chance of reproducing.
What principle states that living things change gradually over time through natural selection?
The theory of evolution by natural selection.
Is it true that through natural selection harmful variations gradually accumulate in a species?
yes
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 is another term for natural selections?
Survival of the fittest
What Accumulate mean?
an increase by natural growth or addition
What are the 4 principles of natural selections?

What is the process gradually changes populations over time?
The process that gradually changes populations over time is called evolution. This occurs through genetic variations, natural selection, genetic drift, and other mechanisms that lead to changes in the traits and characteristics of a population over successive generations.
How do hepful variations accumulate in a specs over time?
Helpful variations accumulate in a species over time through the process of natural selection. Individuals with traits that confer advantages in their environment are more likely to survive, reproduce, and pass those traits to their offspring. Over generations, these beneficial traits become more common within the population, leading to gradual adaptations. Additionally, genetic mutations and recombination contribute to the diversity of traits available for selection.
Minor changes can occur over a few generations the changes produced variations in population this relates to what?
This phenomenon relates to the process of evolution by natural selection, where favorable variations that help individuals survive and reproduce become more common in a population over generations. These minor changes accumulate and can lead to significant adaptations in a population over time.
Why is darwin's theory of natural selection referred to as gradualism?
Darwin's theory of natural selection is referred to as gradualism because it proposes that evolutionary change happens slowly and gradually over long periods of time, through the accumulation of small, incremental variations in populations. This contrasts with other theories that propose sudden and abrupt changes in species.
How do different species come about?
Different species come about through the process of evolution, where genetic variations arise and those that provide a selective advantage are passed on to future generations. Over time, these variations can accumulate and lead to the development of new species with distinct characteristics and adaptations. This process is driven by changes in the environment, genetic mutations, and natural selection.
Is inheritance an important part if the process of evolution?
Yes, inheritance is a fundamental component of evolution. The passing on of genetic information from one generation to the next allows for variations to accumulate and be passed down, forming the basis of genetic diversity and driving evolution through natural selection.
