Yes and so are successful reproduction and the struggle to survive.
Natural selection seems to be the only selection that can drive speciation with powerful adaptive change. Sexual selection seems to stay within the species and both gene flow and genetic drift do not seem to drive speciation very well.
We call this speciation, and is largely driven by evolution and natural selection.
The development of a new species through evolution is called speciation.
When a new species arises from natural selection, it is called speciation. This process occurs when a population becomes reproductively isolated from another population, leading to the formation of distinct species over time.
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.
how is natural selection occurring in the pollenpeepers
Mutation, isolation and natural selection. Google allopatric speciation.
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.
Reproductive isolation through sexual selection is often an important factor in speciation. This type of natural selection can lead to the evolution of reproductive barriers that prevent individuals from different populations from successfully interbreeding, ultimately resulting in the formation of distinct species.
Specation can be used in many ways.
Yes. Without natural selection there might probably still be change, but it would produce a fine gradient of diverging morphologies in every 'direction' of change. Natural selection limits the 'directions' of change, thereby producing distinct morphologies and thus distinct species.
No, the theory of speciation through natural selection and adaptation is based on extensive scientific evidence and research. Scientists aim to understand and explain natural phenomena using evidence-based methods rather than having ulterior motives.
