In the April 14 edition of Nature Jin Meng and colleagues published a paper on the mammalian transitional middle ear.
Meng, Jin, Yuanqing Wang, Chuankui Li. 2011. Transitional mammalian middle ear from a new cretaceous Jehol eutriconodont. Nature 472: 181-185.
In the same issue Paul K. Strother and colleagues published on the earliest evidence for non-marine eukaryotes.
Strother, Paul K., Leila Battison, Martin D. Brasier, and Charles H. Wellman. 2011. Earth's earliest non-marine eukaryotes. Nature 472: 1-5. (the page numbers are probably wrong, my download said this was in volume 000).

End of the Winter Semester
The winter semester has ended (finally!). The piles of grading are gone! Many of us will depart for field work while others will depart for museums. This semester we discussed several exciting and interesting papers. I hope to see all of you again in the fall!
The group would also like to congratulate all graduating members! Congrats and best of luck in your future endeavours!
We congratulate all undergraduate members who are starting graduate school in the fall. We wish you luck (and better see you at discussion in the fall)!
We would also like to say goodbye to Joanna. We hope Drumheller treats her well.

Discussion this week with notes on the Eco-Evo weekly discussion
Last week Carleton was host to Brock Fenton from the University of Western Ontario. He talked about bat evolution with special focus on the laryngeal echolocation. In light of this we are discussing the following papers:
Vaselka et al. 2010. A bony connection signals laryngeal echolocation in bats. Nature 463: 939-942.
Simmons et al. 2008. Primitive early Eocene bat from Wyoming and the evolution of flight and echolocation. Nature 451: 818-822.
I hope to see you all at Mike's place tonight!
This week I am also leading the Biology department's Ecology and Evolution discussion group (12 pm Nesbit 206). We are discussing the following paper:
Barnosky et al. 2011. Has Earth's sixth mass extinction already arrived? Nature 471: 51-57.

Canadian Society of Zoologists Reminder
Hi Evo-Paleo,
Just a friendly reminder that abstracts for the Ottawa meeting of the Canadian Society of Zoologists are due March 16. I hope to see many of you there. I will be presenting on some of my current PhD research. You'll have to come along and see!

Interesting Papers and Temporary Discussion Group Cancellation
I have decided to put the discussion group on hold due to lack of attendance. Two of us did have a good discussion about this week's paper though! Please send me an email when you have a paper suggestion.

Yuan, Xunlai, Zhe Chen, Shuhai Xiao, Chuanming Zhou and Hong Hua. An early Ediacaran assemblage of macroscopic and morphologically differentiated eukaryotes. Nature 470: 390-393.
Wood, Bernard and Terry Harrison. The evolutionary context of the first hominins. Nature 470: 347-352.
Ward, Carol V., William H. Kimbel, Donald C. Johanson. Complete Fourth Metatarsal and Arches in the Foot of Australopithecus afarensis. Science 331: 750-753.

Discussion This Week
This week we are discussing epigenetics and the evolution of the placenta in therian mammals.
Kaneko-Ishino, T., and F. Ishino. 2010. Retrotransposon silencing by DNA methylation contributed to the evolution of placentation and genomic imprinting in mammals. Develop. Growth Differ. 52:533-543.
No fossils this week but an exciting paper none the less!

Third Meeting of the New Year
After a delay due to horrible weather we are ready to resume discussions. This week we will be discussing the evolution of the giraffe neck.
Simmons, R. E., and R. Altwegg. 2010. Necks-for-sex or competing browsers? A critique of ideas on the evolution of giraffe. Journal of Zoology 282:6-12.
Reminders: Early registration for the Canadian Society for Ecology and Evolution (CSEE) ends March 1. If you don't want to pay an extra $75 you better come up with an abstract soon!
