Our species is known to have adapted a lot over the past few hundred or thousand years. Lactose tolerance is a recent adaptation, as well as the ability to break down complex carbs and refined foods. The ability of a group of people to digest different kinds of foods is still affected by natural selection - the more fatty foods Americans eat, the more people with weak hearts die from Heart disease. The more people in Japan and other places eat salty food, the better their livers can deal with it, and so on.
Humans are also getting taller. A few hundred years ago, the average height was about 1 foot shorter than it is today. The average lifespan is getting longer, we're getting smarter, and we're going bald because hairy heads no longer carry a selective advantage.
What else can I help you with?
Why cant new species evolve from natural selection?
New species can evolve through natural selection over long periods of time. However, the process is complex and can take thousands to millions of years due to the gradual accumulation of genetic changes and adaptations. The formation of new species also depends on various factors such as environmental changes, genetic variation, and reproductive isolation.
Who proposed th theory of evolution by natural selection?
Charles Darwin proposed the theory of evolution by natural selection in his book "On the Origin of Species" published in 1859. It states that species evolve over time through the process of natural selection, where individuals with advantageous traits are more likely to survive and reproduce.
What is the scientist that developed the theory of evolution and natural selection?
Charles Darwin is the scientist who developed the theory of evolution and natural selection. His groundbreaking work "On the Origin of Species," published in 1859, outlined the concept that species evolve over time through the process of natural selection, where individuals with favorable traits are more likely to survive and reproduce.
What introduced the concept of biological evolution through natural selection?
Charles Darwin introduced the concept of biological evolution through natural selection in his book "On the Origin of Species" published in 1859. Darwin proposed that species evolve over successive generations through the process of natural selection acting on variations within populations.
Does an individual a population or a species evolve?
A species evolves over time through the process of natural selection acting on individuals within a population. Individuals themselves do not evolve, as evolution refers to changes in the genetic composition of a population over generations.
What process causes adaptations to evolve?
Natural selection
Natural selection will ultimately make a species?

Charles Darwin suggested that species evolve by means of?

What factors could be important for a species to evolve by natural selection?
Environmental change and variation :)

Why do living things evolve?
Natural selection (survival of the fittest) means that valuable adaptations and mutations have the greatest number of surviving descendants.
The mechanism by which organisms evolve is known as?
Natural Selection
How does adaptation fit into natural selection?
Adaptation and evolution all have to do with how an animal or a species depend on there environment. Adaptation is how the species adapts to there environment.Adaptation is caused by evolution by natural selection.
What selection is Darwin associated with?
Charles Darwin is associated with the theory of evolution by natural selection, which explains how species evolve and adapt to their environments over time through the process of natural selection. He is best known for his work on the origin of species and the idea that all living organisms are descended from a common ancestor.
