Evolution by natural selection is currently the only viable theory explaining the diversity of life. However, the mechanism of natural selection is not the only mechanism to affect evolution. There are phenomena such as genetic drift, biased gene conversion, intragenomic conflict, and so on, that aren't exactly the same as natural selection (although they are all intertwined and all affect one another), but do affect the direction of evolution.
No, there are no other theories but the theory of evolution by natural selection that explain so much about evolution.
Darwin's theory of evolution by natural selection was better than other theories of his time because it provided a mechanism (natural selection) to explain how evolution occurs. It was supported by evidence from various scientific disciplines such as geology, paleontology, and morphology. Additionally, Darwin's theory was able to explain the diversity of life on Earth in a simple and elegant way.
The book , On the origin of Species, was the book that shook the world. The book challenged other evolution theories while discussing evolution and the role of natural selection in it.
No, it's exactly the other way around: natural selection causes adaptation.
The theory of mutation proposes that genetic variations occur randomly and are the driving force behind evolution. Natural selection, on the other hand, suggests that organisms with beneficial traits are more likely to survive and reproduce, leading to the prevalence of those traits in a population over time. Together, these theories explain how genetic diversity arises and how species adapt to their environment through the process of evolution.
No, it's the other way around: descent with modification is what you need for natural selection to happen.
It is no longer Darwin's theory, as Darwin has been dead about 130 years. There are no credible alternatives to the modern theory of evolution by natural selection. So, the differences is; the theory of evolution by natural selection is supported by myriad lines of converging evidence and explains the natural phenomenon that is evolution very well. The " conflicting theories " have no evidence supporting them and explain nothing.
It's the other way around: natural selection is the natural process that causes the frequencies of occurence of alleles in the population gene pool to shift.
There are various theories about how humans were created, including religious beliefs such as creationism, which posits that humans were created by a divine being. Scientific theories, such as evolution, propose that humans evolved over millions of years through the process of natural selection. Other theories involve the idea of panspermia, which suggests that life on Earth originated from microorganisms or organic compounds brought here by comets or meteorites.
The velociraptor's natural prey was the protoceratops, but mostly they steal other dinosaurs' and birds' eggs.
By natural selection. (Some natural obstacle prevent the other rhinceros to mix with the black.)
Natural selection and sexual selection are both mechanisms that drive evolution, but they differ in how they shape species. Natural selection is based on survival and reproduction, where individuals with advantageous traits are more likely to survive and pass on their genes. Sexual selection, on the other hand, is based on traits that increase an individual's chances of mating, such as elaborate displays or physical characteristics. While natural selection focuses on survival, sexual selection focuses on reproductive success and mate choice.
