Which of the following are the two key concepts of Darwinian theory of...
According to Darwin's theory of evolution, nature selects the fittest. Fitness is based on characteristics which are inherited. Therefore, there must be a genetic basis for getting selected and to evolve. Some organisms are better adapted to survive in an otherwise hostile environment. Adaptative ability is inherited. Fitness is the end result of the ability to adapt and get selected by nature. Therefore, branching descent (inheritance) and natural selection are the two key concepts of Darwin's theory of evolution.

Branching Descent:
- Branching descent is one of the key concepts of Darwinian theory of evolution. It suggests that all species, living and extinct, are connected through a process of gradual change over time. This means that all organisms share a common ancestor and have diversified into different forms through a process of speciation.
Natural Selection:
- Natural selection is another fundamental concept of Darwinian theory. It is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to future generations. This leads to the gradual change and adaptation of populations over time.
By combining these two key concepts, Darwin proposed a mechanism for how life on Earth has evolved and diversified into the myriad of species we see today. Branching descent explains the relationships between different species, while natural selection accounts for the adaptations and variations that arise within populations. Together, these concepts form the foundation of modern evolutionary biology.
