ancestors
2 Phylogeny repeats ontogeny
w
Every organisms is produced by its
parents
4 None of the above​

Answer 1

Answer:

Haeckel formulated the theory known as the theory of recapitulation or biogenetic law. The theory expresses that "ontogeny recapitulates phylogeny". The development of an organism (ontogeny) expresses all the intermediate forms of its ancestors throughout evolution (phylogeny). For example, the development of the embryo of an animal, from fertilization to gestation or hatching (ontogeny), goes through stages resembling or representing successive stages in the evolution of the animal's remote ancestors (phylogeny).

Struggle for existence is given by Charles Darwin. Recapitulation theory was given by Ernst Haeckel in 1866. Theory of continuity of germplasm was given by August Weismann. Use and misuse of organ concept was given by Lamarck.
