Describe maximum parsimony.

Burka [1]2 years ago

Maximum Thrift is a method / philosophy that considers the shortest tree (in number of transformation steps) the best hypothesis about the phylogenetic relationship of a given set of terminals. Transformation step is the cost attributed to the change of character state in a given branch of the tree, be it the change from one nucleotide base to another, amino acids, or the color of an animal's iris. The fewer transformations, the shorter the tree, and therefore the more parsimonious.  In this method, what programs do is to investigate as many alternative topologies as possible (or all if their array has less than 25 terminals; see more details below) given their character array. Each will be measured, and the shorter (optimal) trees will be retained as the most parsimonious result.

Reasons for seasons<br>​
Sergio039 [100]

Answer:

As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. At different times of the year, the sun's rays hit different parts of the globe more directly. The angle of the Earth's axis tilts the Northern Hemisphere towards the sun during the summer. Without the tilt of the earth's axis, we wouldn't have seasons.
