## Abstract

> This study investigates the role of coding sequence changes in the evolution of postdevelopmental novelty in honey bees, challenging the traditional evo-devo paradigm that emphasizes regulatory changes. Through RNA-Seq experiments, we demonstrate that positively selected, tissue-specific genes with low network connectivity are crucial for the emergence of novel physiological functions in adult honey bees.

## Keywords

`honey bees` · `Apis mellifera` · `RNA-Seq` · `taxonomically restricted genes` · `novel traits` · `gene expression` · `evolutionary biology` · `royal jelly` · `beeswax` · `venom`

## Key Contributions

- Demonstrated that positively selected tissue-specific genes underlie novel physiological functions in honey bees.
- Challenged the evo-devo paradigm by showing that low network connectivity genes contribute to phenotypic novelty.
- Identified the importance of taxonomically restricted genes (TRGs) in the evolution of novel traits.
- Provided insights into the genetic mechanisms governing phenotypic novelty in adult organisms.

## Methods

- Conducted ten RNA-Seq experiments across various honey bee tissues.
- Analyzed gene expression patterns to identify highly expressed taxonomically restricted genes (HE-TRGs).
- Compared gene expression in novel versus conserved tissues to assess the role of coding sequence changes.
- Examined differentially expressed genes (DEGs) between different adult castes (nurses and foragers).
