Evidence from evolutionary immunology confirms that immune system components and specialized immune cells emerged in a chronological, evolutionary sequence across species.

The analysis

The claim states that immune system cells evolved in a specific chronological order. Retrieved papers examining the evolutionary origins of immune genes and cells (such as PGRPs, Tre1 family components, and cnidarian antiviral cells) utilize phylogenetic analysis to map out this chronological appearance across different species. Therefore, the claim is supported by the provided evidence.
