What is everyone writing about?

I found the video, reading the two articles “What is evolution” and “Introduction to evolutionary biology” very interesting because it made me understand more about the species that surround us. One thing that was more interesting to me and that I noticed the most, was that humans are not that different from species and animals, because we all need a partner to help us pass our genes to our offspring. I loved the revolutionary theory, and how evolution occurs though the action of natural selection. I never thought that species, especially the youngsters, inherit things from their parents like humans. I have always heard my mum saying that my eyes looks just like hers, and that I inherited her beauty. But I never thought species could inherit genes from other species. Perhaps take hummingbirds for example, when two parents have long beaks, their offspring will have a long beak. One of the processes of natural selection that was interesting was struggle for existence, because it made me think of humans. The way we struggle to survive. It made me think of crimes, death , day to day life. I have heard of people who were willing to kill each other because of hunger. Why do people commit robbery? People commit robbery for varieties of reasons, like trying to survive, and greed. People try to kill each other for money, and we see the same behavior in animals where they try to kill each other for food instead of money.

  1. I'm not sure what you mean by species inheriting genes from other species. That does occur (a big subject of research now is whether there was gene flow between Neanderthals and Homo sapiens), but the definition of species is that it doesn't share genes with similar, but different species.

    What's interesting about human violence and struggles is how much of this due to behaviors which evolved over thousands of years when we lived in small groups w/ dominance hierarchies and intergroup strife... see the demonic male reading.
