Because human DNA is so very long (with up to 80 million base pairs in a chromosome) it unzips at multiple places along its length so that the replication process is going on simultaneously and more accurately.
It falls to minus 387 degrees Fahrenheit <span />
The study of one type of evidence of evolution is called embryology, the study of embryos. An embryo is an unborn (or unhatched) animal or human young in its earliest phases. Embryos of many different kinds of animals: mammals, birds, reptiles, fish, etc. look very similar and it is often difficult to tell them apart.
Scientific inquiry process discusses to the varied means in which scientists study the natural world and suggest clarifications founded on the evidence derived from their work. Since there are many different kinds of problems that science can address, and the "scientific method" that's taught in class isn't appropriate for every type of investigation because different questions may require different approaches to finding answers. That’s why scientists custom-build the procedures (like a process with many parts) they will use depending on the unique challenges of the problem they are trying to solve.
