No, all life evolves. Bacteria evolve, viruses evolve, protists evolve, plants evolve, fungi evolve and animals evolve. Evolution is driven by Natural Selection. So, no. The evolution of all life on Earth is driven by Natural Selection: all bacteria, plants, animals, mammals, fish, insects, biochemical pathways, behaviours et cetera evolve by Natural Selection.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
natural selection
heritable
Adaptive change and speciation.
Natural selection is a direct product of the environment. A couple of simple examples are: In a cold environment the only plants and animals that will survive will be cold tolerant plants and animals. In a forest of Bears the only animals to survive will be animals that are faster or bigger than Bears. A sudden change in environmental conditions, such as an Ice Age, will see whole populations of some species disappear while only remnants of some species will survive. Those remnants will display either cold tolerance or the ability to withstand the cold by other means ie: clothing or fire.
Nobody, herbs are plants. Plants, like all other living things, evolved by natural selection. Humans only discovered what was already there and found uses for it.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
natural selection is basiclly only the strong survive which means it effects the weak by killing them but bernifits the strong
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
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.
It acts on populations.
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.
natural selection
No. Natural selection requires reproductive variation to work on. Besides reproductive variation and natural selection, there are various forces, biochemical as well as population dynamical, that affect the allelic composition of a population.
he proposed a theory about natural selection
The only thing that causes evolution is Mutations due to forced natural selection of desired alleles.
