The RNA world hypothesis states that the earlier life-forms had relied only on RNA (Ribonucleic Acid) for the purpose of catalyzing the chemical reactions, and storing the genetic information. This hypothesis was proposed by Leslie Orgel, Carl Woese, and Francis Crick.
This hypothesis states that long before the living forms evolved to use DNA as the genetic storage material, the RNA molecules served the purpose of both storing the genetic information and carrying out catalysis, but because of its instability, DNA evolved.
Hence, the answer is RNA world hypothesis.

Answer:
Mist netting is the process in which mist net, that resembles volleyball net is used to capture bats and wild birds for research projects.
<u>There are pros and cons of mist netting:</u>
<u>pros:</u>
- Help to monitor the demographic and population parameters.
- It provide information about the species which are missed using other count methods
<u>cons:</u>
- It can affect the population of birds.
- Survival rates of birds can reduce during capture ifpoor body condition and increased stress
