You seriously believe in Lamarck? Like, I don’t know, I’m not a native speaker, maybe I’m missing something.
How many fucking times do we have to repeat this: TRAITS ACQUIRED DURING LIFETIME ARE NON-INHERITABLE
If you lose your fingers in an industrial accident, your children aren’t going to be born fingerless, are they?
Giraffes don’t have long necks because one little giraffe long, long ago tried really, really hard to grow a longer neck, but because giraffes who had been born with longer necks could compete better than those without, and pass on their genes. And they got those necks due to mutations.
Environmental pressure selects for benefitial mutations, while the mutations themselves are random. That’s literally the mechanism of evolution through natural selection.
Neither am I a native speaker so I worded my joke poorly. I elaborated in another comment but let me point out that in epigenetics, traits gained during lifetime are inherited, but within the range of what mutations “allow”.

Not so fast. Epigenetics is real.
