“Whenever we find, in two forms of life that are unrelated to each other, a similarity of form or of behaviour patterns which relates to more than a few minor details, we assume it to be caused by parallel adaptation to the same life-preserving function.”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
We often infer that similar traits in unrelated species arise from adapting to the same survival need.
In simple terms: Similar traits suggest shared survival pressures.
