This is absolutely wrong.
You can learn Evolution without learning Abiogenesis, and that is the case of majority of biology-related courses.
No universities that I know of are teaching Abiogenesis to undergrad students (eg bachelor degree courses).
And considering that Abiogenesis is still a hypothesis, it is therefore isn’t “science”...yet. Meaning, Abiogenesis is currently still being investigated and researched by advanced biochemist researchers, and there is no agreement (consensus) yet as to which model is the one that started life on Earth.
Until there is consensus on Abiogenesis, Abiogenesis is a specialised area of research, not available (as a course or subject) to any undergraduate students.
So learning biology today, requires understanding of evolution, not abiogenesis.
And as
@ratiocinator , have already said, which ever model of Abiogenesis being accepted in the future, it won’t change anything we have learned about Evolution.
For instance, any biology studying the evolution of horse, only need to study any equine species, and so they don’t need to know where the first cellular organisms. What would be the point that student studying something that isn’t relevant to his course?
