The number of chromosomes does not correlate with the apparent complexity of an animal or a plant:
in humans, for example, the diploid number is 2n = 46 (that is, 23 pairs), compared with 2n = 78, or 39 pairs, in the dog and 2n = 36 (18) in the common earthworm.
Answer:
No, it is not a scientific theory.
Explanation:
- A scientific theory is a proposition that is made to explain the various phenomena that are occurring in nature and it is supported by experiments that have repeatability and well-analyzed results.
- Scientific theories are usually tested in experiments under controlled conditions and verified as well.
- In the given situation, the theory made by the observer is not being tested through any experimentation or quantification and therefore, it is just a hypothesis and not a scientific theory.
competition plays a very important role in ecology and evolution. The best competitors are the ones who survive and get to pass on their genes.
