Compare and contrast microevolution and macroevolution?

Answer 1

a microorganism can or can not be harmful for the host body but a pathogen is a microorganism which is always harmful for the host body.so ALL MICROORGANISMS ARE NOT PATHOGEN BUT ALL PATHOGENS ARE MICROORGANISMS.

Answer 2

Macro-evolution is evolution at and above the species level. Macro-evolution is divergence continued beyond speciation. It occurs because of the continuous, more or less random, variations that reproduction introduces into the genome of every new offspring. Because this variation is more or less random in nature, no two reproductively isolated populations will develop the same variations, and as a result, reproductively isolated populations are bound to diverge genetically (and as a result behaviourally and morphologically), with no set limit.

Answer 3

A Microorganism is a tiny organism which is invisible to the naked eye and can be viewed through a microscope, where as a macro organism is the one visible to the naked eye. One possibility is in term of - scopic or seeing. Macroscopic organisms can be seeing with the unaided eye. Microscopic organisms require a microscope or some other means of visual magnification

Answer 4

Microevolution is when a species slowly changes genes and evolves over time and changes its appearance but it is still the same species. Macroevolution is when species evolves so much that it has turned into a different species all together. Both of these evolution opinions have a species evolving over time in same way and for the same reasons.

Answer 5

Micro-evolution is a perspective on evolution, just life macro-evolution is a perspective on evolution. Micro-evolution is evolution seen at small scales; macro-evolution is evolution seen at larger scales. But they're both perspectives on the same process: reproductive variation and differential reproductive success causing divergence between populations.

Answer 6

Evolution is a general term meaning how species change over time.

This can be split into two groups- micro-evolution and macro-evolution.

Micro-evolution is the change within a species. For example, as humans we are slowly getting taller- however our short ancestors and ourselves were not different species.

Macro-evolution is the change between species, for example the transition from apes to humans.

The fundamental difference between these two types of evolution, other than the fact that one is between species and one is inside a species, is that micro-evolution is accepted everywhere as we can see it happening today, it also does not contradict with various creation accounts from religion. Macro-evolution on the other hand is not accepted by everyone as we cannot see it happening. It also goes against creation accounts such as the one of Genesis in which God created all the creatures as they are today- not as different oes that evolved into todays life on Earth.

Answer 7

Micro-evolution is technically defined as evolution within a species, anything up to speciation without actual speciation. Macro-evolution is all evolution starting with speciation.

It is important to note that these terms do not refer to different processes: they describe the same process, evolution. The only difference is an arbitrary line drawn by humans, like the line drawn between a walk around the block and a cross-county hike: they both refer to the process of walking; the only real difference is distance.

Answer 8

microevolution is small evolution. macroevolution is big evolution. micro mean small and macro means big.
