How do homologous structures provide evidence for evolution?

1 answer:

4 0

The presence of a homologous structure suggests common ancestry, and further suggests that the nearest common ancestor of two organisms had the trait which is homologous. Comparison of several modern organisms with different variations of the same homologous structure can suggest what the original ancestor's actual characteristics were, and comparison of the structure in different organisms can also suggest which organisms are more or less closely related

QUESTION 4

CaHeK987 [17]

Correlational study is used to show the type of association or relationship which exists between two or more variables using statistical analysis. Ken's research shows that there is a relationship between childhood anger management and adult earning.

According to Ken's research, learning how to control anger leads to making more income during adulthood. This signifies a positive relationship between good anger management in childhood and earning made during adulthood.

Similarly poor anger management in childhood leads is associated with low earning during adulthood.

Hence, Ken's research shows that there is a relationship between childhood anger management and adult earnings.

What trait variation did Charles Darwin observe after studying the Galapagos finches? (5 points)

zloy xaker [14]

The finches of the same genus had different characteristic on the different islands of the Galapagos. They had different graded beaks sizes and shapes. In some islands, finches had sharp beaks for stabbing their prey. In other islands, the fiches had short stout beaks for grain-eating. This is a case of allopatric speciation where a population of the finches diverged to.adapt to the habitats in the different islands and also claim different niches

If you wanted to make a prediction about an event that required complicated analysis of data which tool would be the most helpfu

erik [133]

If I was going to make a prediction for a scientific data thing I would always go to plotting it as a graph – with graphics calculators you can get it to even give you an equation to follow.

The only problem with this is if you're wanting to predict data beyond the range of your given data points (extrapolating), because it is generally viewed as inaccurate.
