Earlier studies have indicated that a gene called FOXP2, possibly involved in brain development, is extremely conserved in vertebrates, except for two notable mutations in humans. This finding suggested that this gene may in some way be involved in the evolution of language, and was thus dubbed by the popular press "the language" gene. See, for instance, this and this for some recent research

So, the day has finally arrived - the Big Move to SEED scienceblogs. Go check out the brand new front page and all the old and new bloggers there.My new blog, a fusion of all three of my blogs, will be a new brand, with a new name - A Blog Around The Clock, reflecting my age and musical taste, my usual blogging frequency and the area of my scientific expertise, all in one title.The Banner was

BIO101 - Bora Zivkovic - Lecture 4, Part 3In the first two parts of this lecture we tackled the Origin of Life and Biological Diversity and the mechanisms of the Evolution of Biological Diversity. Now, we'll take a look at what those mechanisms have produced so far - the current state of diversity on our planet.The Three DomainsThe organisms living on Earth today are broadly divided into three

Now we move to explanations of the mechanisms by which diversity arises.Although traits can be inherited by non-DNA ways, and DNA sequence does not neccessarily translate directly onto the traits, in the long term the

A moment later, you hear a lion approaching and, out of the corner of your eye, you see the lion running towards you.What happens next? You start running away, of course. How does that happen?

DonorsChoose is a nifty website that collects in one place many educational programs and initiatives. If you are a teacher you can pick one or more of those to support, or you can add one of your own. If you are a teacher who needs something, this is the place to ask for it. If you are a blogger, you can challenge your readers to donate to the program of your choosing. Donations are easy to

Also imagine that the ten insects are quite large and that the meadow has only so much flowers, food and space to sustain these ten individuals and not any more. Also imagine that the genomes of those ten insects are identical, except for one individual: that one has a mutation

How Genotype Affects PhenotypeBIO101 - Bora Zivkovic - Lecture 2 - Part 3One often hears news reports about discoveries of a "gene for X", e.g., gene for alcoholism, gene for homosexuality, gene for breast cancer, etc. This is an incorrect way of thinking about genes, as it implies a one-to-one mapping between genes and traits.This misunderstanding stems from historical precedents.

Cell Division and DNA ReplicationBIO101 - Bora Zivkovic - Lecture 2 - Part 1In the first lecture, we covered the way science works and especially how the scientific method applies to biology. Then, we looked at the structure of the cell, building a map of the cell - knowing what processes happen where in the cell, e.g., the production of energy-rich ATP molecules in the mitochondria.In the third

Welcome to The Tar Heel Tavern, the showcase of North Carolina blogging goodness. In keeping with the theme of this blog, as well as the timeliness of the edition coinciding with college graduations and (almost) end of the school year, the entries today all have something to do with learning, teaching or education. It is not a huge edition, but it is all high quality blogging. So, let's get

BIO101 - Bora Zivkovic - Lecture 1 - Part 4Cell-cell interactionsCells do not exist in complete isolation. For a coordinated function of cells in a tissue, tissues in an organ, organs in a system and systems in the body, cells need to be able to communicate with each other. Each cell should be capable of sending chemical signals to other cells and of receiving chemical signals from oter cells,

It is usually tightly coiled forming chromosomes in which it is protected by proteins.Each of the two strands of the DNA molecule is a chain of smaller molecules.
