Finches Determine Sex of Offspring

As you know if you read my blog, Trivers Willard is an important theoretical construct which has been tested numerous times. TW works in some species, not in others, and overall, that should be predictable (accroding to TW).

It turns out that finches control the sex of their offspring, and do so in a way that TW would predict, apparently. There is a paper in Science that I’ll probably eventually get to writing up for you, and in the mean time, here’s a quick news report from Scientific American.

See if you can figure out how Trivers Willard is working here, and why the important theoretical aspect of this research is glossed in this news report.

A new blog that could be good

…I am trying to rid the word dilettante of its negative connotations and use it to highlight my interest in scientific research of all kinds. My area of expertise is chemical engineering and food science, however this does not prevent my interest in any other research.

I like any and all science, so this is my playground where I can properly discuss other areas outside my expertise without getting a bad formal peer review!

We like dilettantes. So let’s see how The Science Dilettante develops!
