Your skin colour is based on millions of years of evolution depending on where your ancestors lived and their living conditions. Skin colour varies on where you live (or came from). Children will have different tones or shades of skin from their parents due to human skin colour having multiple genes. This is an example of polygenic inheritance.
Explanation:
see the picture below to see how different skin colours depend on where they live:
photosynthesis is what organisms use to create food and energy. this comes from the sun. and cellular respiration is carbon dioxide that comes from the animal after photosynthesis
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.
