Can the trait of rate of development be acted upon by natural selection?
Any morphological and behavioral trait that is in hard inheritance, genetic inheritance. Remember, all organisms are variants and these traits vary from organism to organism and so natural selection selects the best adapted trait among the population of organisms against the immediate environment. The trait that confers better survivability and reproductive success, So, evolution, the change in allele frequency over time in a population of organisms, occurs. Only natural selection confers adaptive change leading to speciation. Epigenetic changes are not adaptive changers.
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 is the process by which only the suited for organism environment survives?
natural selection
What does it mean that an organism is homozygous recessive for a trait?
That organism has two recessive alleles for that trait, one from each parent. It will display the recessive trait.
Natural selection is the only mechanism of evolution that will lead to?
Adaptive change and speciation.

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
