Look at this happy healthy creature who I spotted crossing the busiest road in my suburb this evening at dusk.

This one was studiously ignoring the myna birds who were outraged that an echidna was passing through their territory, while also being ignored by the sulphur crested cockatoos who were coming home to their night time trees.

A nearly gapless #genome sequence of the #echidna, an egg-laying mammal with multiple #sexChromosomes, helps researchers to track genomic reorganization events that gave rise to a highly unusual #sexDetermination system.

related to the system of the #platypus which was the cover story in my book "Der Kuss des Schnabeltiers" / "The birds, the bees, and the platypuses." 15 years later I can't remember how that worked but I loved the story.

EurekAlert!Unraveling the events leading to multiple sex chromosomes using an echidna genome sequenceThe short-beaked echidna (Tachyglossus aculeatus)  is one of Australia’s most iconic animals. Belonging to a unique group of mammals called “monotremes” (with the platypus as the other prominent member), echidnas may at first glance be mistaken for a weird-looking hedgehog, but they are in fact egg-laying mammals.  An international team of authors, led by Guojie Zhang and Qi Zhou at Centre for Evolutionary & Organismal Biology at Zhejiang University, Yang Zhou from BGI-research and Frank Grutzner from Adelaide University now present an almost gapless genome sequence of the short-beaked echidna. This work is part of the international Vertebrate Genome Project, and hosted in the VGP Genome Ark Database. The authors used the new data to better understand the evolutionary origin of the highly complex configuration of multiple sex chromosomes which is characteristic for monotremes. The work is published in the open science journal GigaScience.

Ok, must be me, and marsupials have an issue with me. On walk Tuesday evening and come round a corner and an echidna is waddling down the road. I stop to take some photos and it just keeps coming, Everything seemed to be in slow motion, then again it could be that echidnas are pretty slow. Before I knew it, it was pushing through my legs. Not sure if this can be considered an attack 😂🤣 but I was having flashbacks to Xmas eve.
