Scientist Charles Darwin gave many arguments about this issue in his ‘Mate Selection Theory’ (Theory of Sexual Selection). He wants to say that some differences between men and women are created because they are helpful in the evolution of a species. Many biologists believe that the purpose of this difference is to protect the female mate from possible attacks by enemies.
The female bird has to sit in the nest all the time to hatch the chicks from the egg. At this time, he has almost no defense system. Therefore, the color of female birds is usually plain, so as not to be easily noticed by chil-vultures. In contrast, their male counterparts have attractive colors and decorations

Search engines use robots that crawl webpages across the internet to determine what content they contain and, in turn, what the pages are about. These bots scan the code, picking up the written text, images, videos, and more that appear on web pages to gather all information possible. Once they’ve gathered enough intel about the type of information available on each page and determined that this content will be useful to their searchers, they add these pages to their index. The index is essentially all possible web results that a search engine stores to provide to a potential searcher.

Search engines assess what the best result is based on what searchers are looking for, as well as what other information already exists online. When someone searches, their algorithm matches the user’s search query to the relevant information in their index, providing searchers with an accurate answer to their query. The platforms then use hundreds of signals to determine the order in which the content will appear for each searcher. These signals are what SEO experts try to master.

It’s important to note that Google does not release specifics about its algorithm or process, so it’s impossible to know exactly what factors impact indexing and rankings. SEO, therefore, isn’t a perfect science, and even when it seems that all optimizations have been implemented, it often requires patience and continual tweaking to see results.
