  1. Across an extraordinary variety of species, animals vocalize at a strikingly consistent rate of approximately two to three acoustic events per second (around 2.8 Hz), constrained by the brain's inherent capacity to process auditory stimuli.

  2. Xenobots are microscopic, programmable biological machines constructed entirely from living cells without any genetic modification. Measuring less than a millimeter, they lack traditional mechanical parts and are entirely organic, biodegradable, and derived primarily from embryonic stem cells of the African clawed frog (Xenopus laevis).

  3. The history of life on #Earth is often viewed through a strictly #Darwinian lens of competition—a relentless, zero-sum struggle where every organism fights for a larger slice of a finite resource pie. In this narrative, nature is, as Alfred, Lord Tennyson famously wrote, "red in tooth and claw," dominated by predation, #parasitism, and the survival of the fittest.

  4. Mutation accumulation theory (Evolutionary biology 🧬)

    The mutation accumulation theory of aging was first proposed by Peter Medawar in 1952 as an evolutionary explanation for biological aging and the associated decline in fitness that accompanies it. Medawar used the term 'senescence' to refer to this process. The theory explains that, in the case where harmful ...

  6. Food for thought #Samples from higher #paleolatitudes were on average smaller, but contained #outliers with the largest #sizes, highlighting the need to analyze entire #distributions. #Lithology and #collection differences need to be accounted for when evaluating #size differences across #space (#polar #gigantism) and #time (#Lilliput #effect). Similarly, differences in #facies may affect #species #determination
