Giant prehistoric penguin is reconstructed in New Zealand Kairuku was 30cm taller and 50% heavier than emperor penguin, the largest of the modern era
We are not born sterile, but with gut flora that seems to be transmitted across the placenta that is strongly influenced by maternal diet. Also, super freaky, gut flora composition can effect personality/behavior and learning abilities in mice. I now feel like I should eat things that will placate the bacteria in my intestines that are apparently controlling my life...

The largest brain study of its kind had found a gene linked to intelligence. Searching for a genetic explanation for brain disease, the scientists stumbled upon a minute variant in a gene called HMGA2 among people who had larger brains and scored higher on standardised IQ tests. The variant occurs on HMGA2 where there is just a single change in the permutation of the four 'letters' of the genetic code.

Social Stress Changes Immune System Gene Expression in Primates The ranking of a monkey within her social environment and the stress accompanying that status dramatically alters the expression of nearly 1,000 genes, a new scientific study reports.
Nova--Regulating Genes. Study how the mutations in different regions of the DNA impact the expression of genes. Predict how the mutations impact the development of the creature’s traits. And finally, observe the developed creature and explain how the mutation gave rise to any changes.
