 As stipulated in the hypothesis of Darwin, individuals best adapted to their environment are likely to survive, reproduce, and evolve. The objective of this study is to deepen and strengthen the natural selection hypothesis by examining whether there are one or more locations within the DNA sequence of Cumacea of the mitochondrial 16S rRNA gene that could correlate not only the segments of the sequence (windows) but also the Cumacea to their environment.

+In this section, we will describe our data, followed by an outline of the main steps used in data preprocessing and the software aPhyloGeo. 
 
 \subsection{Description of the data}
 The study area is located in a northern region of the North Atlantic, including the Icelandic Sea, the Denmark Strait, and the Norwegian Sea. The specimens examined in this study were gathered during the IceAGE project (Icelandic marine Animals: Genetic and Ecology; Cruise ship M85/3 in 2011; \cite{brix_iceage_2014}), which investigated the deep continental slopes and abyssal waters around Iceland \citep{meisner_prefacebiodiversity_2018}. The sampling period for the specimens included in this study was from August 30 to September 22, 2011, and they were collected at depths ranging from 316 to 2568 m.  Information about the sampling plan, sample processing, the steps of DNA extraction, PCR amplification, sequencing, and the extracted and aligned DNA sequences are available in the article by \cite{uhlir_adding_2021}.
