Richard Dawkins, in his seminal work The Selfish Gene, argued that we are all simply elaborate gene-replicating machines. If you look at how many resources an animal will sacrifice for their relatives, it corresponds exactly to the percentage of shared DNA. There are many examples in nature, and Dawkins covers them extensively. This is a fact of life, not anything to do with personality or culture.

DNA is the foundation of life in every sense.
