In France at least, the answer is yes, these positions exist. The positions you need to look for are either called "PRAG" (for PRofesseur AGrégé dans l'enseignement supérieur) or "PRCE" (for PRofesseur CErtifié affecté dans l'enseignement supérieur). There exists a list of such positions (warning: big xls spreadsheet) and I count a few that mention "biologie" for example. These are teaching-only positions in universities, or sometimes "grandes écoles" (which are pretty much the same as universities except that they have fewer students, students had to take a competitive exam to get in, education starts at the 3rd year level, and the focus is often more on engineering).
However, landing these positions is not easy.
- They are very competitive: there are few of them, and they are in high demand.
- To become a "PRAG" you need to be professeur agrégé, as the name indicates. This is done by passing the agrégation, which is a national competitive exam. Similarly to become "PRCE" you need to be a professeur certifié, which requires passing another national competitive exam (easier than the agrégation).
- Both of these are civil servant (fonctionnaire) jobs. Professeurs agrégés usually teach in high school (sometimes in middle school), and professeurs certifiés teach in middle and high school. If you win the national competition, you have to take up a post (and you're unlikely to obtain a PRAG or PRCE position your first year unless you're brilliant and lucky). If you don't, then you will lose your position unless you have a compelling reason, which certainly won't help you build the seniority/experience necessary to obtain a PRAG/PRCE position.
As professeur agrégé you would also have the possibility of teaching in a prépa, including biology. This is a special post-secondary studies pathway consisting of two intensive years of training (for the students) before the students take up the national competitive exams to enter a grande école. This covers the first two years after high school (and usually the content of the courses is larger than the content of the first two years of university). Once again, obtaining a position in a prépa is rather difficult and is a combination of brilliance and luck (and networking...).
Upside: there is zero research pressure in these positions as you will not have any duty (or time) to do research.
Other than that, I don't think there exist any teaching-only positions in France. All other academic positions (maître de conférences, chargé de recherche...) are either teaching+research or even research-only. It is not surprising that all the job ads you found emphasized a strong research record in France: by law, research is mandatory, and university departments are only evaluated (and hence receive funding) through research.
