Question

Modern theory of evolution called synthetic theory is based on: 
  1. Genetic and chromosomal mutations
  2. Genetic recombination and natural selection
  3. Reproductive isolation
  4. All the above


Solution

The correct option is D All the above
Modern evolutionary theory is essentially a combination of Charles Darwin's concept of natural selection, Gregor Mendel's basic understanding of genetic inheritance, along with evolutionary theories developed since the early 20th century by field biologists, population geneticists, and more recently by molecular biologists. The hottest area of research concerning the mechanisms of evolution today is in evolutionary developmental biology (commonly known as evo-devo). It focuses on discovering and understanding genetic changes that alter embryonic development and lead to new features in species lines.
