Do selection target the genome region or entire euchromatin or hetrochromatin that is segregated in the nucleus? With 38 amniote chr genomes and their Hi-C data, we show despite dramatic chromosomal reshufflings, ancestral t.co/67kdI9nyqs

Hi y'all. In the midst of [gestures all around], I managed to write a thing. If you work with mitochondrial DNA sequences in groups such as birds, butterflies, or snakes, you might find it interesting. Feedback welcome. The "Driving W Hypothesis" for low mtDNA diversity: doi.org/10.1101/2025...

new work from the lab. Degeneration of Y chromosome does not seem to be one-way street. As a refugium of transposons @Alex Suh @valentinapeona.bsky.social , Y chromosome can recruit some genes by accidental TE burst: www.sciencedirect.com/science/article/pii/S1673852725002243

The difference between doing a project and presenting it. An observation can lead to many avenues of explorations before focus turns to a specific discovery. Presenting it, in a talk / paper, follows inversely, with broad perspectives coming before & after the specific discovery.

We are organizing a symposium in the 4th AsiaEvo Conferenence this December in #Kunming about #appendage featuring the Palentologist Xing Xu at IVPP, Dev. biologist Cheng-Ming Chung from USC and evodevoist @MonteiroLab Antonia Monteiro from NUS. Submit your abstract now!

There will be a special session during @official-smbe.bsky.social 2025 this year to introduce the Mol Biol Evol studies in China: smbe2025.scimeeting.cn/en/web/index.... My student Huangyi and postdoc Jing Liu will be giving a talk in two other symposiums. See u in Beijing!

We have met them already, but when in Beijing, make sure not to miss this amazing set of talks by the winners of the Graduate Student Excellence Award, presented at a dedicated symposium at the start of #SMBE2025. 🙌 Details on the website: smbe2025.scimeeting.cn/en/web/progr...

@wenjuanma84.bsky.social and I have assembled a great list of speakers on sex chromosome evolution of a wide range of species! Look forward to see you @official-smbe.bsky.social smbe2025 in Beijing on in the Zoom room in July!

Zhu, @zhouqi1982.bsky.social et al. produce a chromosome-level genome assembly of the Amur rat snake (Elaphe schrenckii) using HiFi and Hi-C data (1.69 Gbp; N50 = 215 Mb; 97.4% BUSCO), an important resource for studying snake evolution. 🔗 doi.org/10.1093/gbe/evaf086 #genome #snake

Huangyi He from Zhejiang University is on today! Huangyi's research focuses on the evolutionary and developmental mechanisms behind sperm heteromorphism and sex chromosome evolution in Drosophila. 🪰 More ⬇️ and follow Huangyi on social media X: @HuangyiH92641

The great part is that he is wearing AirPods Max

Wenjuan Ma and I are organising a symposium "Evolution and regulation of sex chromosomes and sex determination" at #smbe2025 @official-smbe.bsky.social this summer in #Beijing with Tatianan Giraud as our invited speaker! We look forward to your abstract
