"Almost all biological notions, going from 'life' to 'bird' to 'great tit', are created and defined by people/scientists."
There are different ways to define things. Genetic makeup defines species, races etc. in biology and its not just some random it lays eggs or it has 8 arms etc. stuff, its not just characteristic etc. its the DNA or RNA etc.
A whale is far from a fish and so is platypus from a bird. Its a bit like if someone takes a test compare three persons, two of whom are a mother and her son and the third one is not related, but for example looks a lot more like the child than his mother.
