El origen de la especies

The video explains how species have evolved over billions of years, forming a diverse array of life. It describes species as populations that are reproductively isolated and how new species form through evolutionary processes. Geographical isolation, such as mountains and rivers, can lead to speciation by dividing populations and driving genetic differentiation. Natural selection further enhances these differences, leading to new species. Speciation is typically slow but can accelerate with rapid environmental changes.

What is a species according to the video?

• A group of organisms that can interbreed with any other group

• A population of organisms that are reproductively isolated

• A collection of organisms living in the same habitat

• A group of organisms with similar physical characteristics

How do evolutionary processes contribute to the formation of new species?

• By causing immediate changes in physical traits

• Through gradual genetic differentiation over generations

• By allowing species to interbreed freely

• Through sudden environmental changes

What role does geographical isolation play in speciation?

• It causes immediate extinction of species

• It prevents any form of adaptation

• It divides populations, leading to genetic differentiation

• It allows populations to remain genetically identical

Which of the following is NOT a factor that can lead to geographical isolation?

• Continental drift

• Identical habitats

• Migration

• Natural disasters

How can rapid environmental changes affect speciation?

• They slow down the process of speciation

• They have no impact on speciation

• They cause all species to become extinct

• They can accelerate the adaptation and differentiation of populations
