A Representative ideograms of three main karyotypes (2n = 30/32/38) observed among the true crocodile species analyzed in the present study showing Zoo-FISH results after using CSI-1, OST-1, OST-4, and OST-19 probes, and the 18S rDNA distribution. Arrows indicate the 4 main chromosomal rearrangements involved in karyotype differentiation from a putative ancestral 2n = 32. B Ancestral state reconstruction of diploid chromosome number using maximum parsimony. The phylogenetic relationships were adapted from Oaks (2011) and Colston et al.

The tiny pseudoscorpion 'Chelifer cancroides' evolved venomous claws independently from scorpions & spiders. Proteomics & transcriptomics of its venom revealed the first genuine pseudoscorpion toxins, including brand-new antimicrobial compounds! #2026MMM pubmed.ncbi.nlm.nih.gov/34416254/

Fig. 3. Documentation of venom release in C. cancroides after electrical stimulation of the chelal hand. The flow of current was facilitated by a conductive fluid (CF). A liquid indicator (LI) was used for the experiments to visualize venom release. A, B) Venom extraction using Type 1 capillaries with larger inner diameter. These capillaries partially cover the movable finger (MF) while the venom (V) is being collected. Before electrical stimulation, the movable finger is in a relaxed state (A). When electrical power is applied, the venom tooth pinches the glass wall of the capillary, causing the release of venom (B). C, D) Venom extraction from the fixed finger using Type 2 capillaries with an inner diameter of about 10 μm. These capillaries covered only the venom tooth and lamina defensor. The application of electricity caused the immediate release of venom, which replaced the brownish liquid indicator at the tip of the capillary.

Dogs evolved to eat your leftovers! Comparing dog & wolf genomes revealed dogs have up to 30 EXTRA copies of the amylase gene (AMY2B) that helps digest starch. This is a key genomic signature of living alongside humans & table scraps for thousands of years 🐕 www.nature.com/articles/nat... #2026MMM

Adapted from Axelsson et al. 2013 Fig 2c: Histogram showing the distribution of diploid amylase copy number in wolf (n=35, blue) and dog (n=136, red). Dogs carry more copies of the starch-digesting gene AMY2B than wolves. Additional copies make dogs better than wolves at digesting starchy foods like grains & vegetables.
