Answer 2

Answer:

Option (c) Darwin is the correct option. Darwin showed that embryo development follows some definite laws.

Explanation:

According to darwin, the genetic connectedness of various animals can be strongly supported by embryonic resemblances.

• He interpreted Von Baer's laws in terms of evolution demonstrating that by finding a common larval or embryonic form, relationships between different groups can be found.

• He also states that development alters the structures present at the embryonic stage leading to differences or modifications among different adult species or organisms.
• Therefore according to him, embryo development follows some definite laws in terms of descent with modification-

1. Embryonic similarities can lead to the understanding of common descent between 2 or more groups of organisms.
2. Development induces modifications that produce different structures for the organisms to adapt to certain conditions.
