00:01 The concept that the preferred hypothesis is the one that is simplest is phonetics, cladistics, the principle of past money, maximum likelihood, or both b and d.

00:13 Okay, so let's go through the verse two.

00:16 So, phonetics.

00:18 Phonetics is where, instead of looking at the phylogenetic relationship, the evolutionary history, it's instead looking at other similarities, like morphology.

00:30 So, blasting organisms based on similarities, not shared evolutionary history.

00:41 So that's phonetics.

00:43 Cladistics is the opposite.

00:46 Cladistics is what we used to.

00:48 Pladistics is grouping them based on their shared history.

00:52 So, classing organisms based on shared common ancestors.

00:59 So these are two ways of grouping animals together.

01:05 So let's throw those up and focus on c and d.

01:10 So these are both two methods to employ, the principle of past money and maximum likelihood.

01:16 And they're pretty similar.

01:17 In both cases you're looking for the most likely option, but there are some differences.

01:23 So the principle of pass money is looking for the minimal number of changes in the tree.

01:31 So minimizing the number of character state changes...
