Haeckel’s biggest error was an idea he called the biogenic law, which never became mainstream biology.
With his drawings and accompanying descriptions, Haeckel promoted the idea that “ontogeny recapitulates phylogeny,” also called the biogenic law.
Cabbages and most vegetation emit chemicals called biogenic volatile organic compounds, or BVOCs, that are mostly undetectable by humans.
According to BBC News, in response to all these disruptions, plants will emit greater levels of fragrant chemicals called biogenic volatile organic compounds (BVOCs). hat will then alter how plants interact with one another and defend themselves against pests, according to a major scientific review.
In response to all these disruptions, plants will emit greater levels of fragrant chemicals called biogenic volatile organic compounds.
A small group of chemically related molecules, known as biogenic amines, regulates various neuropsychological processes and behaviour patterns.
According to the heads of a recent research review, "the world may already be becoming more fragrant, as plants have already begun emitting more smelly chemicals" known as biogenic volatile organic compounds (BVOCs), the BBC's Earth News service reports.
Dopamine and serotonin are members of a class of neurochemicals called biogenic amines, which function in neuronal circuitry throughout the brain.
Finally, and most importantly, the exhalations of humans and animals are biogenic, meaning that they are essentially "carbon neutral" (unlike the emissions from burning gasoline).
Now Kakani Katija and John Dabiri at the California Institute of Technology have developed a way to estimate the extent of "biogenic" mixing.
