Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated. Sharks are egg-laying ...

Alu elements, labeled with green fluorescence in these human chromosomes, make up more than 10 percent of the human genome. (Image from Bolzer et al., (2005) Three-Dimensional Maps of All Chromosomes ...

It turns out humans aren’t the only ones checking out what their neighbors are doing when looking for ideas on how to make life easier. All species adapt and evolve in a variety of ways. In fact, ...

We share the planet with a huge diversity of plants and creatures. But we can see similarities between organisms that live continents apart or are very different in other aspects. One reason for this ...

Animals can evolve separately but end up evolving toward other species, too, or even spontaneously evolve the same ...

Similar phenotypic traits such as anatomical structures and physiological functions often evolve independently in different organisms. Nonetheless, the evolutionary paths leading to these convergent ...

During development, embryonic cells sculpt three-dimensional tissues. Although cell polarity is commonly analysed along one, and sometimes two, dimensions, this perspective illustrates how ...
