When Charles Darwin published his radical theory of evolution by natural selection in 1859 it was attacked by many early biologi
irina1246 [14]

Answer:

Empirical evidence of his ideas

Explanation:

The scientific process involves the formulation of hypotheses that enable to answer questions about the real world, and then to carry out experiments or observations that are used to confirm (or reject) such predictions. In the last 160 years, Darwin's ideas on 'descent with modification' have constantly been subjected to experimental assessment, and obtained data confirmed his observations. For example, molecular evidence based on the DNA and RNA -which constitute the genetic material of all living organisms- has shown the conservation of this process. In consequence, molecular evidence has been used to construct 'evolutionary' phylogenetic trees from DNA/RNA sequences. Moreover, evidence in genetics has shown the critical role played by mutations in the mechanism of natural selection proposed by Darwin, thus also confirming his theories. These are only some examples, and supporting evidence confirming Darwin's ideas has been collected from different research fields ranging from ecology to molecular biology.

Creators who "level" communicate purposefully, honestly, and responsibly.
vredina [299]
<span>This is incredibly true. The top way to level up, or receive a promotion, is to have proper communication.
