Answer:
The correct answer is- adaptive radiation
Explanation:
Adaptive radiation is the evolutionary process which allow the evolution of many species from a single species because some population of that species get into an environment which is different from their old environment in terms of food availability, predators, etc.
So the first bird that evolved the ability to fly branched into many different species due to habitat change is an example of adaptive radiation. The most famous example of adaptive radiation is Darwinian finches which evolved from an ancestral species of south America that reached Galapagos island.
Answer:
Genetic code
Explanation:
Genetic code refers to the set of rules by which the information encoded in the genetic material is translated into the proteins. The genetic code is present on the genes in the form of triplets of nucleotides called codons which specifies the specific amino acid.
The codon system of the genetic code rules allows the 4 different nucleotides to form specific amino acids by the combination of the four different nucleotide in the triplets.
Thus, Genetic code is the correct answer.
Answer:
The hole is lack of knowledge of the concept of natural selection, especially its physical properties and how it operates.That is what made those organisms with fitted traits to resit the selective pressures and therefore survive than others with less resistance .
Basically,he lacked the knowledge of the concept of variation as the driving mechanisms of natural selection he theorised. Darwin did not understand how variation among different species of organisms physically emerged to made these organisms resistant to the selective pressure, and therefore emerge as the survival of the fittest in the population.
