Summary
The theory of evolution is that all animals and humans are descended from species that exist previously. Evolution does not have steady replacement for older species with new species. Over time different traits evolve species into another species. Patterns and similarities and differences are evidence of evolution in a species. There is also evolution from different types of fossils, when a species of animal dies they usually leave their remains i the form of fossils, most people have heard of dinosaur fossils. Through fossils and the studying of them scientists can tell the difference between the creatures we have now and the creatures in the past. The scientists call these fossils transitional fossils which tell the difference between spices over time. The first traditional fossil we are going to talk about is the Archaeopteryx which is the fossil of a bird like dinsour which is not the direct ancestor to birds but it is close related to it. Then there is the Autonomy and Development of the creature. With scales and feathers they are part of the homologous structure which is that their evolution is due to that of a common ancestor, which is cool since most species don't really relate to their ancestors. Then there are the analogous structures which happen with fish and dolphins where they are not connected to their ancestors. Then some species now are vestigal which means their original function when they were a dinsour was lost. Then there are mutations which happen with the species over time that can change it to have different functions. Thats all that you need to know about evolution.

For the Keystones in order to succeed you will need to know a lot of study strategies to pass the test. Click on an actual article about the cells in question and read those articles, or you could look it up on google scholar. Google scholar is a alternative to google where you can search up articles about education. If looking up or reading articles don't help you, you could watch youtube videos about the subject. If that doesn't help right it down in a note type of function that you like which would help you learn better. There are many strategies to learn new things you should use them.
