‘Superarm’ helps male octopuses deliver sperm to females Specialized appendage responds to female sex hormones, allowing males to find sex organs in the dark

Here’s a real-life riddle: which underwater creature has evolved progesterone receptors in one of its specialized arms, and uses that specialized arm to locate its targets and deliver sperm, even in total darkness? www.science.org/content/arti... 🧪 #evolution #marinebiology

Newly Discovered Organism Could Represent a Whole New Branch in The Tree of Life It's not every day that biologists announce an entirely new branch of life, and this one has been hiding under their noses for years.

Slipped-strand mispairing: a major mechanism for DNA sequence evolution - PubMed Simple repetitive DNA sequences are a widespread and abundant feature of genomic DNA. The following several features characterize such sequences: (1) they typically consist of a variety of repeated motifs of 1-10 bases--but may include much larger repeats as well; (2) larger repeat units often inclu …
