there is because if you look at a fossil and you look at an animal or human now you would see a huge difference.
The four pieces of evidence that scientists point to as proof of natural selection are the fossil record, biogeography, homologous structures, and observable natural selection in action. These pieces of evidence all support the idea that organisms have evolved over time through the process of natural selection.
Evidence for evolution includes the fossil record, comparative anatomy, molecular biology, and observed instances of natural selection. These different lines of evidence all support the concept of biological evolution occurring over time.
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.
Biological evidence of evolution includes fossil records showing transitional forms, comparative anatomy across different species revealing similarities in bone structures, and genetic similarities among related species. Additionally, the observation of natural selection leading to adaptations in organisms over time supports the concept of evolution.
No. Natural selection requires reproductive variation to work on. Besides reproductive variation and natural selection, there are various forces, biochemical as well as population dynamical, that affect the allelic composition of a population.
Selection is not always of the most fit to survive.

Yes, penguins, like all animals, have gone through natural selection. Scientific evidence supports this notion.
All of the biological sciences. The theory of evolution by natural selection is the backbone of biology.
