Although the anatomical differences in echolocation in bats and whales are strong evidence of independent evolution, recent research has found that several genes involved in hearing are nearly ...

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 ...

Species adapt and evolve in strikingly similar or distinct ways. Uncover the different pathways between convergent and divergent evolution. The theory of evolution, worked out in the nineteenth ...

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 characteristics in totally separate groups. Birds and bats can both fly using ...

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