How do animals change over time?
a) Species change over time; some traits become more common, others less. This process of change is driven by natural selection. The traits that become more common are the ones that are “adaptive” or “increase fitness” (that is, a creature’s chances of living longer and producing more offspring).
How an organism has changed over time?
Evolution is an important field of study for scientists. It covers the study of changes organisms have undergone over time in response to different factors in their environment. Evolution occurs through natural selection, and is a force that has shaped every organism living today.
How do species change over time to adapt to their environment?
Species can change over time in response to changes in environmental conditions through adaptation by natural selection acting over generations. Evolution results primarily from genetic variation of individuals in a species, competition for resources, and proliferation of organisms better able to survive and reproduce.
What are three examples of species changing?
Here, a few examples of animals evolving in real-time.
- The lizard with extra sticky feet.
- The shrimp that lost its eyes.
- The owls that are changing color.
- The fish that’s migrating earlier.
- The bedbugs with super-strength.
- The mouse that’s immune to poison.
Are any animals still evolving?
Evolution Continues In stable conditions, there’s no reason for a species to change. Climate change is placing environmental stressors on animals right now, therefore several species are evolving faster than ever before. We can see that animals have evolved in our lifetime, and humans are still evolving, too.

What is the toughest animal to kill?
Share All sharing options for: Tardigrades are the toughest animals on Earth. What would it take to kill them all? In the end, there will be tardigrades. If a cataclysm wipes out most of life on the planet — including humans — it’s likely that tardigrades will survive.
