New Cambridge Element in the Philosophy of Biology series—fully #openaccess! @thomasreydon.bsky.social explores how evolutionary theory crosses over from biology into other fields, showing how these crossovers embody a broader style of reasoning: 'evolutionary thinking' bit.ly/48z3h36 #HPbio #evosky
Book cover of “The Scope of Evolutionary Thinking” by Thomas A. C. Reydon, in the Cambridge Elements: The Philosophy of Biology series. Against a black background, the title is surrounded by Ernst Haeckel’s illustrations of marine organisms—radial, symmetrical forms in vivid blues, oranges, reds, and greens.

Why studies about reconstructing the past based on contemporary DNA makes me think of the streetlight effect

News in the history of molecular biology. The Science History Institute in Philadelphia has acquired a huge archive of correspondence and other scientific material from the pioneers of molecular biology (Franklin, Klug, Perutz, Delbrück etc, with items from Crick and Watson, too). 1/n
History of Molecular Biology Collection
This unparalleled collection includes Rosalind Franklin's historic 'Photo 51,' which revealed the double-helix structure of DNA.

Some scientists also think that historians do not know enough about the science to write about its history, which of course is not the case for good historians. Same for philosophers.

For an individual on average, or the average individual perhaps, but not for any two specific individuals. It is one thing to made a mathematical calculation and another to make sense of it.

My point was that I do not think we can make any legitimate inferences for individuals. Anyway, this may be of interest: plato.stanford.edu/entries/heri...

90% heritability for height means that 90% of the variance in height across individuals in that specific population, place, and time is statistically associated with genetic differences. What it does not mean is that your height, or my height, or any individual's height is 90% genetic.

Here is a substack post about heritability, related to my comment below:

"Today, estimates from twin studies attribute up to 90% of an individual’s height to their genetic makeup."

This is not corrrect! What heritability studies show is that at the population level 90% of the differences in height are due to genetic differences.
