Both are "wrong" (within the context of the general understanding, analysis and discussions). Within a broader, deeper holodynamic-systems context (as covered by the Key Principles of Life, for Life) both are "right" in that the system we experience is newly forming and being formed by intelligent interaction with the physical environment.
Lamarck was ahead of his time: We physically affect our genetic structure (and children's inherited characteristics) by what we think, feel and believe - as required by the Key Principles.
According to some estimates, our physical system is rapidly being refreshed somewhere around 18.54 x 1042 times each second (the inverse of the Planck time). In other words, the universe, and everyone and everything in it, is newly cycling into physicality trillions of times each second. It is being intelligently designed by us and the greater unconscious-collective within which we exist. That is to say, "it" -- the system, comprising our bodies, planet and the entire universe -- is being "intelligently designed, and re-designed" many trillions of times each second. And each part within is co-creating the system as experienced. As physicist John A. Wheeler remarked, we live within a participatory universe.
As introduced elsewhere on this site, science and religion are "sister belief-systems", in that both objectify physical and meta-physical realities, respectively. Both rely on, and posit theories based on an objective separation of perceiver from some 'functionally separate' aspect of existence (physical and meta-physical). Scientific and religious beliefs are reliant on a fundamental disconnect between individual (part) and whole (universe); between individual-consciousness and collectives of unconscious/nonlocal cooperation and influences; between One and All.
