Question

Evolution of heart from one to two, three and four chambered proves:

• A. Biogenic law of Haeckel.
• B. Neo darwinism.
• C. Lamarkism
• D. hardy weinberg's law.

Answer 1

The correct option is A Biogenic law of Haeckel.

The biogenetic law given by Ernst Haeckel states that the developmental stages of embryos of the animal follow a link common to ancestor or in other words, it goes through stages resembling or representing successive stages in the evolution of the animals' ancestors- ontogeny recapitulates phylogeny. The evolution of heart from one to two three and four chambers proves this biogenetic law.

So, the correct answer is 'Biogenic law of Haeckel'
