What are 3 pieces of evidence that scientists combine to determine evolutionary relationships among species?
Genetic features, morphological features and behavioural features.
How does Darwin's theory of evolution explain microevolution but not macroevolution?
Those terms need to be done away with. There is no such division in the theory of evolution by natural selection, even in Darwin's time. There is evolution and speciation. One flows seamlessly into the other over time and we have myriad pieces of evidence supporting this.
What makes evolution a therory?
Evolution, the change in allele frequency over time in a population of organisms, is fact. The theory of evolution by natural selection explains much about the fact of evolution. That is what make a theory, explanation. Facts are useful, but uninteresting. Theories explain facts by gathering many convergent pieces of evidence and putting it into a logical and consistent whole.
What are the causes of microevolution?
The same as the causes of so called macroevolution. The change in allele frequency over time in a population of organisms. By mutation, natural selection, genetic drift and gene flow. I would rip to pieces about half of the biology text books of America over this constant misunderstanding of evolutionary theory they perpetrate.
Why do scientists believe evolution occurred?
Charles Darwin developed the Theory of Evolution by Natural Selection before most of the fossil evidence for the theory existed. He looked at the micro-evolution practised by pigeon breeders, the evidence on the Galapagos Islands and elsewhere, and realised that evolution was the only explanation that made sense. He saw that related species were to be found in close proximity, evidence of evolution from a single parent species, whereas a single act of Special Creation ought to have placed the species anywhere on the globe where the environment was suitable.The fossil record shows clear evidence of evolution over a period of more than a billion years. Certainly, at first, there were no transitional species among the many species that had been found, although scientists saw much that did confirm the Theory of Evolution. That has changed, because many transitional species have been found. A recently discovered 220-million year old fossil, Odontochelys semitestacea, is a new species of turtle that had a fully formed shell on its underside, but only a small partial shell on its back, extending from its backbone. As well as a partial shell, Odontochelys semitestaceaalso had ribs that had begun to widen, thus demonstrating that the fully developed shell of later turtles evolved from the ribs of earlier species. Tiktaalik roseae is the name of a newly discovered lobe-finned fossil fish from the late Devonian period, that is a transitional form to amphibians, with basic wrist bones and simple fingers, as well as the robust ribcage necessitated by existence out of water. Odontochelys semitestacea and Tiktaalik roseae are two more pieces in the jigsaw that shows conclusively how life on Earth evolved from earlier species.Scientists can now use DNA evidence from modern species to support the fossil record, as further evidence of evolution.

Genetic features, morphological features and behavioural features.
Name two pieces of evidence that scientists have used to base the Continental Drift Theory on?
i dont even kno ok you people shouldf know

Is fossil record considered scientific theory?
Probably more in the line of many converging pieces of evidence in support of theory. Theory is explanation and fossils are just mineralized bones in the rock. which need and explanation. The fossil record supports the theory of evolution by natural selection and, some say, the theory of punctuated equilibrium.
What strategy do historians use to synthesize evidence and draw conclusions?
Corroborating it with other pieces of evidence

What did Alfred Weneger try to prove?
Alfred Weneger was trying to prove his theory of Continental Drift. Many other scientists before him had the same theory, but they never could prove it. He had five pieces of evidence.
What are three pieces of evidence that scientists use to support the theory of the continental drift?
The 3 pieces of evidence is: 1. fossils 2. climate 3. glaciers Wegner found out that the same fossils were found on a different continent. There was this tropical plant (i forgot whats it called) was found at a icy cold region so then the plant couldn't grow there only by continental drift. The glaciers have scratches on them which was one of the evidence. I hope this really helped :D
What are pieces of information collected during an investigation?
evidence
What term do scientists give to the pieces of a cell?
the sex cells are different
What is the comparison between a art museum with the natural history museum?
Both types of museums will have a collection of pieces, and will display some of these pieces. In an art museum these pieces are works of art. In a natural history museum these pieces are historical artifacts.
What is two pieces of evidence that English is the global?
global warming?
