My Flashcards

Definition

Meaning

A modern revival or adaptation of Lamarck's theory of evolution, emphasizing the inheritance of acquired characteristics.

The belief, arising after Darwin, that organisms can pass on traits acquired during their lifetime to their offspring, often discussed in critiques of strict neo-Darwinism or in certain epigenetic contexts.

Linguistics

Semantic Notes

Primarily a historical and philosophical term in evolutionary biology. Its use is almost exclusively metadiscursive (discussing theories, not applying them). Not a term used to describe actual biological processes in mainstream modern science.

Dialectal Variation

British vs American Usage

Differences

Spelling: In British English, the hyphen is more consistently retained (neo-Lamarckism with capital L). In American English, it may sometimes appear as 'neo-Lamarckism' or less commonly as 'Neolamarckism'.

Connotations

Identical in both varieties. Connotes a heterodox, largely abandoned, or historical evolutionary theory. May have slightly stronger historical association with late 19th/early 20th century debates in British biology.

Frequency

Extremely low frequency in both. Possibly marginally more frequent in British academic historical texts due to specific national scientific history.

Never used.

Academic

Used in history and philosophy of science, theoretical biology. E.g., 'The paper examines the persistence of neo-Lamarckism in early 20th-century botany.'

B2
  • Scientists once debated between Darwinism and neo-Lamarckism.
  • The idea that learned behaviours can be inherited is a form of neo-Lamarckism.
C1
  • The late 19th century saw a significant, if ultimately futile, revival of neo-Lamarckism in several biological disciplines.
  • Modern epigenetics is sometimes cautiously discussed in relation to historical neo-Lamarckist concepts, though the parallels are highly limited.

Learning

Memory Aids

Mnemonic

Think: NEO (new) + LAMARCK (the scientist Jean-Baptiste Lamarck) + ISM (a doctrine). A new version of Lamarck's old idea that giraffes' long necks, stretched from reaching, are passed to their babies.

Conceptual Metaphor

IDEAS ARE ORGANISMS (it is a 'revival' or 'persistent strain' of thought), THEORIES ARE BUILDINGS (it has 'foundations', is 'dismantled').

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid confusing 'neo-lamarckism' with 'Lamarckism' (ламаркизм). The 'neo-' prefix is crucial for the later, revised theories.
  • Do not translate as 'неодарвинизм' (neo-Darwinism), which is its direct opposite.

Common Mistakes

  • Mispronouncing 'Lamarck' as /læˈmɑːrk/ instead of /ləˈmɑːrk/.
  • Using it as a synonym for any non-genetic inheritance (overgeneralization).
  • Spelling: 'Neolamarkism' (missing 'c').

FAQ

Frequently Asked Questions

No, the core premise of the inheritance of acquired characteristics as formulated in historical neo-Lamarckism is rejected by modern evolutionary biology, which is based on neo-Darwinism and genetics.

Lamarckism refers to Jean-Baptiste Lamarck's original early 19th-century ideas. Neo-Lamarckism refers to later, post-Darwinian revivals (late 19th/early 20th century) that attempted to modify and modernize Lamarck's concepts in light of new biological discoveries.

No. While some epigenetic mechanisms involve non-genetic inheritance of certain states, this is highly specific, regulated, and operates within the framework of neo-Darwinian evolution. It does not validate the broad, direct inheritance of acquired physical traits central to neo-Lamarckism.

Historically, figures like the American paleontologist Edward Drinker Cope and, in some aspects, the British writer Samuel Butler. It had adherents in botany and microbiology into the early 20th century.
