Can the trait of rate of development be acted upon by natural selection?
Yes, the rate of development can be influenced by natural selection. Traits that affect an organism's development can impact its survival and reproduction, thereby subjecting them to selection pressures that may favor certain rates of development over others. Over multiple generations, individuals with beneficial rates of development may be more likely to pass on their genes, leading to evolutionary changes in development rates within a population.
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.
WHAT NATURAL SELECTION CAN ONLY ACT ON WHICH TRAITS?
Natural selection can only act on traits that have a genetic basis, meaning they are heritable and can be passed from one generation to the next. These traits must also affect an organism's fitness, influencing its ability to survive and reproduce in its environment. Additionally, natural selection operates on phenotypic traits, which are the observable characteristics resulting from the interaction of genetics and the environment. Traits that are not expressed or that do not impact survival and reproduction are not subject to natural selection.
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.
Does natural selection act on genotypes?
Indirectly, yes it does. But it can only act on genotypes through their phenotypes.
Why are only inherited traits not acquired one necessary for the process of natural selection?
Because the offspring of an organism with a desirable inherited trait is more likely to survive than the offspring of an organism with a desirable acquired trait (because the offspring of an organism with a desirable acquired trait will not have its parent's desirable trait).

Problems with the theory of survival of the fittest?
It can only explain certain situations. And it's just one of the aspects of natural selection.
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.
Which does natural Which does natural selection affect?
natural selection is basiclly only the strong survive which means it effects the weak by killing them but bernifits the strong
Is natural selection a process or a result of a process?
Natural selection is only the result of changing environments, mutation and the variation resulting therein. Natural selection is the process of adaptive change and the main mechanism of evolution that leads to speciation. Natural selection is a process as mutation and variation are grist to the mill of natural selection.
Natural selection requires that individuals in a population are?
Natural selection requires that individuals in a population are
Which of the following is the most powerful evolutionary force in large populations over time?
Only natural selection could be the answer here as natural selection is the main driver of adaptive change leading to evolutionary change and speciation in large populations.
What does natural selection only act on?
It acts on populations.
Compare and contrast natural selection and artificial selection?
Natural selection is when contemporary species rose from ancestors that survived due to their physical characteristics in their habitats. A well-known example is the Galapagos Islands and how the animals on the islands adapted to their environments. Darwin convinced the biology world that diversity in organisms came from evolution (descent without modification). Artificial selection is when humans intentionally breed animals for certain traits. Unlike natural selection, where only the fittest survive, artificial selection is for human's likings. Many crops that are grown are part of artificial selection.
Is inheritance a requirement for natural selection?
Yes it does. Without variance in the organisms genome, that gives variance to the phenotype, there would be nothing for natural selection to select from.
Why are vestigial structures not removed by natural selection?
Nature selects against only harmful traits
