“Ontogeny recapitulates phylogeny” was Haeckel’s answer―the wrong one―to the most vexing question of nineteenth-century biology: what is the relationship between individual development (ontogeny) and the evolution of species and lineages (phylogeny)? In this, the first major book on the subject in fifty years, Stephen Jay Gould documents the history of the idea of recapitulation from its first appearance among the pre-Socratics to its fall in the early twentieth century.

Mr. Gould explores recapitulation as an idea that intrigued politicians and theologians as well as scientists. He shows that Haeckel’s hypothesis―that human fetuses with gill slits are, literally, tiny fish, exact replicas of their water-breathing ancestors―had an influence that extended beyond biology into education, criminology, psychoanalysis (Freud and Jung were devout recapitulationists), and racism. The theory of recapitulation, Gould argues, finally collapsed not from the weight of contrary data, but because the rise of Mendelian genetics rendered it untenable.

Turning to modern concepts, Gould demonstrates that, even though the whole subject of parallels between ontogeny and phylogeny fell into disrepute, it is still one of the great themes of evolutionary biology. Heterochrony―changes in developmental timing, producing parallels between ontogeny and phylogeny―is shown to be crucial to an understanding of gene regulation, the key to any rapprochement between molecular and evolutionary biology. Gould argues that the primary evolutionary value of heterochrony may lie in immediate ecological advantages for slow or rapid maturation, rather than in long-term changes of form, as all previous theories proclaimed.

Neoteny―the opposite of recapitulation―is shown to be the most important determinant of human evolution. We have evolved by retaining the juvenile characters of our ancestors and have achieved both behavioral flexibility and our characteristic morphology thereby (large brains by prolonged retention of rapid fetal growth rates, for example).

Gould concludes that “there may be nothing new under the sun, but permutation of the old within complex systems can do wonders. As biologists, we deal directly with the kind of material complexity that confers an unbounded potential upon simple, continuous changes in underlying processes. This is the chief joy of our science.”

The basis for the movie of the same name, an astonishing tale of one lock of hair and its amazing travels–from nineteenth-century Vienna to twenty-first-century America.

When Ludwig van Beethoven lay dying in 1827, a young musician named Ferdinand Hiller came to pay his respects to the great composer, snipping a lock of Beethoven’s hair as a keepsake–as was custom at the time–in the process. For a century, the lock of hair was a treasured Hiller family relic, until it somehow found its way to the town of Gilleleje, in Nazi-occupied Denmark. There, it was given to a local doctor, Kay Fremming, who was deeply involved in the effort to help save hundreds of hunted and frightened Jews.

After Fremming’s death, his daughter assumed ownership of the lock, and eventually consigned it for sale at Sotheby’s, where two American Beethoven enthusiasts, Ira Brilliant and Che Guevara, purchased it in 1994. Subsequently, they and others instituted a series of complex forensic tests in the hope of finding the probable causes of the composer’s chronically bad health, his deafness, and the final demise that Ferdinand Hiller had witnessed all those years ago. The results, revealed for the first time here, are the most compelling explanation yet offered for why one of the foremost musicians the world has ever known was forced to spend much of his life in silence.

In Beethoven’s Hair, Russell Martin has created a rich historical treasure hunt, a tale of false leads, amazing breakthroughs, and incredible revelations. This unique and fascinating book is a moving testament to the power of music, the lure of relics, the heroism of the Resistance movement, and the brilliance of molecular science.

This study was funded by the Chief Scientist Office, Scottish Government, as part of its Rapid Research in Covid-19 Programme and was conducted between July and December 2020. The study was completed by a team of researchers at the University of Glasgow and supported by 20 partners from the third sector. The research focused on the impact of Covid-19 restrictions (‘lockdown’) for four groups already experiencing exclusion, isolation and marginalisation: people having a disability or long-term health condition (DHC); People involved in criminal justice (CJS); Refugees and people seeking asylum who were at risk of destitution (RAD); People surviving domestic abuse or sexual violence (DASV). As a rapid research project, the study aims to understand and report on the impacts of Covid-19 restrictions as they are happening, in order to contribute to better responses to it; the analysis presented may be further developed and modified. It has been recognised that social research is needed alongside medical and health research to understand the effects of this pandemic on individual and collective wellbeing. Already evidence has established that social inequalities are shaping Covid-19 risk and impact, but the evidence base is not yet well-established for Scotland.
