Sexual selection and natural selection are both mechanisms that drive evolution, but they differ in their focus. Natural selection acts on traits that increase an organism's chances of survival and reproduction in its environment, while sexual selection specifically targets traits that enhance an individual's ability to attract mates and reproduce. This can lead to the evolution of characteristics that may not necessarily improve survival, but increase reproductive success.
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.
Natural selection is a process in biology where organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to their offspring. Over time, this leads to the evolution of species as those with beneficial traits become more common in a population.
Natural selection and sexual selection are both mechanisms of evolution, but they differ in how they shape species. Natural selection acts on traits that affect an organism's survival and ability to reproduce in its environment, leading to adaptations that increase survival and reproduction. Sexual selection, on the other hand, acts on traits that affect an organism's ability to attract mates and reproduce, leading to the development of traits that enhance mating success. In summary, natural selection primarily influences survival and reproductive success in the environment, while sexual selection primarily influences mating success and reproductive opportunities.
The Galapagos Islands influenced Charles Darwin's theory of evolution by providing him with diverse and unique species that showed variations in traits, leading him to develop the concept of natural selection as a mechanism for evolution.
Charles Darwin proposed the theory of evolution by natural selection in his book "On the Origin of Species" published in 1859. It states that species evolve over time through the process of natural selection, where individuals with advantageous traits are more likely to survive and reproduce.

We call this speciation, and is largely driven by evolution and natural selection.
Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature for the characteristics they possess that make them more apt to survive. Because of natural selection, evolution occurs.

A new and better adapted species.
The book "On the Origin of Species by Means of Natural Selection" was written by Charles Darwin.

different species originated from other species
Accidental selection is the process of evolution in a subset of a species due to circumstances like a natural disaster.
