The theory of biological evolution is often misunderstood. Here you will find accurate information on this powerful field of biological study, presented in clear language for everyone to understand and enjoy.
Next time you’re stung, remember this: You have just been stabbed by the modified reproductive organs of a lady bee!
Maiacetus was about 8 1/2 feet long, lived a little over 47 million years ago, and is interpreted as an amphibious whale that rested on land but hunted at sea.
The modern whale’s blowhole clearly gives it a survival advantage. But how did natural selection, a blind thoughtless process, first get started building this fantastic contraption?
Since 1982 the GALLUP survey group has been conducting an ongoing poll on the American public's acceptance of evolution.
A mutation rate is the number of mutations which occur on average per generation. Mutation rates are determined by comparing the DNA of offspring to parents, and counting up the differences.
In 1961, Marshall Nirenberg cracked the genetic code, finally showing us the DNA language used by genes to build proteins. Today we are still working to figure out how those genes, and the proteins they build, affect our overall structure and appearance.
