How did life begin?

Biology
1 answer:
Feliz [49]3 years ago
6 0

Explanation:

Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.

The main causes of climate change are: Humanity's increased use of fossil fuels – such as coal, oil and gas to generate electricity, run cars and other forms of transport, and power manufacturing and industry. Deforestation

Volcanologists can predict eruptions—if they have a thorough understanding of a volcano's eruptive history, if they can install the proper instrumentation on a volcano well in advance of an eruption, and if they can continuously monitor and adequately interpret data coming from that equipment.

How does the coloration of beetles help explain Darwin's dangerous idea
Gennadij [26K]

Not sure what you mean by dangerous. Charles Darwin had a theory on evolution called Natural Selection. This theory of his essentially states that the organisms that adapt best and most successfully to changes in their surroundings are more likely to survive. A coloration change in beetles would explain this because the color change may help them blend in with their surroundings better, thus escaping predators and having a greater chance of survival. These beetles, due to their success, will become prevalent, meaning that the other beetles will phase out because they have not adapted well to the environment.
