3. true
Lamarck was one of the first scientists to propose that species evolve by natural selection. Lyell was one of the first to say that Earth must be far older than most people believed. Lamarck's inheritance of acquired characteristics is has become a widely accepted scientific theory.

work of Lamarck
He enunciated the law of use and disuse, which states that when certain organs become specially developed as a result of some environmental need, then that state of development is hereditary and can be passed on to progeny. He believed that in this way, over many generations, giraffes…

8. true
Lamarck's inheritance of acquired characteristics has become a widely accepted scientific theory. Fossils proved to Darwin that species can evolve. The term "fitness" refers to an organisms ability to outrun its hunters. Darwin published his findings soon after returning to England from the voyage of the Beagle.
