Life began as prokaryotic cells. These bacterial life forms still do very well. But the need for food and space And other pressures in the sea Influenced life To achieve more complexity. The ones who lived could reproduce, Soon the study of taxonomy was introduced. Now we can name all living things By their phylum and their class. Then it’s order, family, genus And the species name comes last.
CHORUS Environments Don’t stay the same. Always rewriting The rules of the survival game. Life forms all need water, shelter, food and oxygen, Ways to reproduce And grow without getting eaten.
Oh and I, I will survive. There are qualities about me That will help my children thrive. Got variation in our genes. Yeah, you know just what it means. I will survive. I will survive!
The fossils of life forms that are now extinct Inspired many scientists to stop and think That all these little changes Happening through history Have added up to make a great diversity. And now we have fungus and plants And animals that are well made for their environments. Some structures are homologous and some formed separately. Some are no longer needed. That’s vestigiality!
