Humans in the 21st century use their thumbs extensively to operate touchscreens on cellphones. Imagine a scenario, where the human population evolves to have more dexterous thumbs over the next 300 years. Which of the following is a Lamarckian explanation for this evolutionary change (and, therefore, would an incorrect evolutionary mechanism?)     humans that develop more dexterity in their thumb over their lifetime due to frequent use of cellphones pass that ability to their children     humans that were born with a mutation for more dexterous thumbs have more children     thumb dexterity is a dominant trait

Human Evolution

Human evolution is the process of evolution of humans from early man to anatomically modern humans. The process of evolution in humans leads to the gradual development of traits like bipedalism. Humans are the highly social animals that make them the most advanced animal on Earth.  Human evolution is an outcome of interaction among the following processes:
