What are four methods that scientists use to study homologies in genetics?
The four methods that scientists use to study homologies include using HSPs in Viterbi algorithm, bi-directional Viterbi algorithm, biased hidden Markov models and using HSPs to position target regions. They also use Data sets which include Training data set of human genes and Validation and testing data sets of homologous genes.
What is the difference between evolution and theories of evolution?
Evolution is a process, theories of evolution are theories which explain that process
What term describes the changes that an organism goes through?
It is called "evolution".
What is spontaneous evolution?
Spontaneous evolution is evolution that is not moderated by intentional beings and actions. Most evolution, in other words. Usually we call non-spontaneous evolution (ie. evolution that *is* moderated by intent): breeding.
What is evolution in action?
it is the "action" in evolution

How does genetics help in the study of evolution?
Genetics allows us to chemically study the evolutionary history of organisms in a way that cannot be disputed. You cannot argue against basic chemical signiture homologies.
What is the definition for homologous?
anatomical homologies
What are chemical homologies?
you can always check wikipedia
What are the different types of homologies?
Alakane and Alkene
Why are vestigial structures evidence of evolution?
Because of the morphological homologies they display with similar structures in other extant and extinct lifeforms, following, like virtually every other morphological or anatomical feature of life, the nested hierarchies of biology.
What are three areas of Lamarck's hypothesis of evolution?
Main points of Lamarck's theory are the following . 1 Changing environment produced need for new organs . 2 there is an increase in size of organs and organisms . 3 use and dis use of organisms . Inheritance of acquired characters .
How did the evolution of the Virginia colony between 1607 and 1625 reveal the impact of new world condition on the aims and expectations?
corn
What are homologies and why are they important in classification?
Homologies have similar characteristics due to being related. You are able to see homologies by comparing the anatomies of different living things, look at the cellular similarities and differences, look at the embryological development and compare and look at vestigial strutures. Even though leaves of plants look different and have different shapes and functions, they are homologous because they share a common ancestor.
What is the definition for Anatomical Homologies?
The definition of developmental homologies is something that can be viewed in the fossils of certain animals that point to and evolutionary change in their current incarnations. For example snake fossils when compared to current snake skeletons show that the ancient relatives of snakes actually had feet and over time they feet pulled closer into their body eventually developing into the snakes of current times.
