This surprised Dr Rosenthal and Ms Garrett, who had expected that natural selection would have changed the DNA, and thus the composition of the resulting protein.

ECONOMIST: A hitherto-unknown way to evolve

Dr Kirkpatrick points out that the spectrum (and thus the chemical composition) of a methane dwarf is very similar to that of Jupiter.

Thus, the composition of benthic communities (the term indicates a dependency on the bottom) will rely partly on the availability of organic substances falling all the way down to the seabed.

Thus this change in the composition of unemployment requires a different solution.

As well as using the rover's X-ray spectrometer on Whitewater Lake and Kirkwood to determine the chemical elements present, and thus get a better idea of their mineralogical composition, the team needs to work out the order and position of the rock layers to tell them something of their relative ages.

Thus it is often inaccurate to make conclusions about summaries of data without consider the composition of the data.
