lamarckian
C2Academic, Technical, Historical
Definition
Meaning
Relating to the theory of evolution proposed by Jean-Baptiste Lamarck, which posits that an organism can pass on characteristics acquired during its lifetime to its offspring.
By extension, describing any concept, process, or belief in the inheritance of acquired characteristics or a view of evolution emphasizing adaptation and use/disuse of organs. Often used metaphorically to describe cultural or social traits perceived as being passed down and developed through practice.
Linguistics
Semantic Notes
Primarily used as an adjective (Lamarckian theory). Can be used as a countable noun (a Lamarckian) to denote a person who subscribes to Lamarckism. In modern biology, it is largely a historical/contrastive term, as the core mechanism was superseded by Mendelian genetics and the modern synthesis.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or spelling. Usage is confined to identical academic/biological contexts.
Connotations
In both varieties, it carries connotations of a superseded, pre-Darwinian (or alternative) evolutionary theory. May have a slightly pejorative sense when used in mainstream biology, but a neutral or positive sense in historical or specific niche studies.
Frequency
Extremely low frequency in general discourse. Equal, very low frequency in both UK and US academic biological or history of science texts.

[Rarely, if ever, used]
Academic
Standard term in history of biology and evolutionary theory. 'The Lamarckian elements in his thinking were later criticised.'
Everyday
Virtually never used.
Technical
Precise term in biology and history/philosophy of science to denote a specific theoretical position.
Examples
By Part of Speech
verb
British English
- [No standard verb form. Theoretical: 'to Lamarckianise' is non-standard.]
American English
- [No standard verb form.]

Examples
By CEFR Level
- [This word is far above A2 level.]
- [This word is far above B1 level.]
- Lamarckian ideas about evolution were popular before Darwin.
- The scientist rejected the Lamarckian theory.
- Modern epigenetics has sparked renewed, albeit cautious, interest in certain Lamarckian phenomena.
- The debate between Weismann and the Lamarckians was pivotal for modern biology.
Learning
Memory Aids
Mnemonic
Think: 'A marquee' (sounds like Lamarck) is a temporary structure. Lamarck's theory of traits acquired in a lifetime (temporary) being passed on is also an idea that didn't last permanently in mainstream science.
Conceptual Metaphor
KNOWLEDGE/CHARACTER AS AN INHERITABLE ASSET (cultivated and passed on).

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating it as a general term for 'evolutionary'. It is a specific historical theory. The Russian equivalent 'ламаркизм' or 'ламарковский' is direct and accurate.
Common Mistakes
- Misspelling: 'Lamarkian', 'Lamarckean'.
- Using it as a synonym for 'evolutionary' in general.
- Confusing Lamarckian inheritance with Darwinian natural selection.

FAQ
Frequently Asked Questions
The core Lamarckian mechanism of inheritance of characteristics acquired through use and disuse during an organism's lifetime is not supported by mainstream biology. However, some niche phenomena like epigenetics are sometimes discussed in relation to 'Lamarckian-like' processes, though they are mechanistically different.
Lamarckism proposes directed variation based on need/use, with inheritance of acquired traits. Darwinian evolution (via natural selection) proposes random variation, with the environment selecting beneficial traits that are already heritable.
Yes. A 'Lamarckian' is a person who supports or believes in Lamarckism.
In the history and philosophy of science, sociology (e.g., discussing the 'Lamarckian' transmission of cultural traits), and sometimes in discussions of learning or memetics.
