The evolutionary model of brain development predicted that the complexity of neural connectivity should have increased as brains became larger and the creatures more complex.

Most people might be surprised to learn that the human genome has not been fully sequenced. Gaps still remain that have not yet been bridged because of the nature of the DNA sequence coupled with past limitations on DNA sequencing technology.

European dippers are making the news lately, including science news in Wales.^1-3

These riparian habitat birds are indicators⁴ of freshwater stream quality, as noted below. Scientists study them to learn how badly freshwater streams are polluted—such as by non-biodegradable (non-decaying, indigestible) plastic waste products.^2,3
