I’m a bioinformatics PhD student at EMBL-EBI and the University of Cambridge but I’m originally from Berlin.

I’m mainly working on genomics using next-generation sequencing data. My current thesis project is about the regulation of tRNA expression in mammals.

Here’s my …

comment How did the first sexual animal come to exist?
Actually your text already convinced me, concerning the number of times sex evolved (hence the edit).

comment How did the first sexual animal come to exist?
I’m not sure I would agree with “no brainer”. As far as I know, sexuality has only evolved once. Also, could you expand a bit on the heterogamy argument? In particular, wouldn’t the same apply to plasmids? Yet we don’t see anything particularly resembling sexual selection emerge from that. /EDIT: Your answer might actually contradict my first assertion (I should have read the full post first) – I’m still interested in an answer to the second.

comment How did the first sexual animal come to exist?
I’ve had to edit your answer, “just one theory” sounds a bit too similar to the “just a theory” creationist canard for comfort. I’m wary that it might feed the common misconceptions about what makes a scientific theory.

comment Why is Portuguese man o' war considered a colony?
@har-wradim I seem to have misinterpreted what scarce information I could find about siphonophorae. Thanks for the link. Having said that, a cursory reading of the article actually seems to support my understanding (although the “develop independently” part of my answer is certainly imprecise and suggest that they assemble into colonies after embryogenesis). I need to spend more time on this.

comment Aren't current explanations for the evolution of human cooperation a little too reductionist?
Inclusive fitness proponents will tell you that this explanation is completely wrong, by they way (without being an expert, I tend to agree).

revised What is the difference between naive and adjusted p-values in a GWAS study?
The p-value explanation was actually wrong.

comment Why has evolution made neurons use spiking?
You should read up on how neurons work. You admitted that you don’t know this, yet it directly answers your question.

comment Why it is rare for person to get infected with two Pathogens?
Your example is actually quite bad because the “common cold” is often an infection by several strains of viruses (and even bacteria) simultaneously.

comment Is light required for seed germination?
The riddle can be solved by realising that different plants have different requirements, and that some requirements are “soft” – i.e. not absolutely necessary but nevertheless beneficial. I’ll let somebody else with more knowledge provide a more in-depth answer – my comment wasn’t meant to imply that this is a bad question.

comment Is light required for seed germination?
Given that germination often happens underground, the answer seems trivially “no”, doesn’t it?

comment How easy is it to carry out de novo sequence assembly?
tl;dr: It’s blood, sweat and tears. I haven’t been involved in this myself yet but I know people who are. Depending on the complexity of the genome, you’ll get tons (they got in the order of 1M) non-overlapping contigs.

comment Why are there no wheeled animals?
@terdon Hehe, and I likewise forgot about the G’Kek. But re-reading the Uplift Saga is time well spent anyway. ;-)

comment Does evolution destroy functional sequences much faster than it creates them in any large-genome animal with low reproductive rates?
Biology.SE is actually very unhappy about creationism questions. However, I think this one’ll pass.
