How many different species of guppies are there?
The Guppy is a single species. There are many variations (varieties) that have been developed by breeders but they are all the same species and can interbreed.
Compare and contrast organism and species?
Organism: Anything that posses all of the characteristics of life is known as an organism. All living things have an orderly structure, produce off springs, grow and develop, and adjust to changes in the environment. Species: A species is a group of organisms that can be interbreed and produce fertile off springs in nature. If individuals in a species never produced, it would mean an end to the species' existence on earth.
What do fossils reveal about changes in species over time?
The changes in different species penis sizes.
What group of organisms that can breed and produce fertile offspring?
A group of organisms that can mate and produce offspring which can themselves mate is called a species.
Polyploidy instantly results in a new plant species because it?
changes a species' number of chromosomes.:) no problem
When do you say that a creature has evolved so much that it is no longer the same species?
When a creature undergoes significant changes in its genetic makeup and physical characteristics that prevent it from successfully reproducing with individuals of its ancestral population, it can be considered a different species. Reproductive isolation is a fundamental principle in defining species, meaning that if two populations can no longer interbreed and produce fertile offspring, they are considered separate species.
What is the subject of the book The Edge of Evolution?
The Edge of Evolution: The Search for the Limits of Darwinism is about the evolution and that it can produce changes within species, but there is a limit to the ability of evolution to generate diversity, and this limit (the "edge of evolution") is somewhere between species and orders.
How does natural selection produce genetic variation within a species?
It's mainly mutations in the DNA and recombination of chromosomes that produce the genetic variation. Natural selection then favors those changes that give rise to greater reproductive success.
The principle that living species were descend with changes from other species over time is referred to as?
The theory that living species were descend with changes from other species over time is referred to as evolution.
Do organisms have to be the the same species in order to breed and produce offspring?
No, organisms of different species can breed and produce offspring. Donkeys and horses can breed and produce mules but mules cannot produce offspring.
What evidence support evolutionary theory?
Fossils depict gradual changes in species over geologic time. This was one primary bit of evidence for Darwin's theory. Another was the similarity in species separated by geography. Race circles are one example of this. Variations introduced by pigeon breeders demonstrated that variations resulted in inheritable traits. Today we also have DNA, which clearly demonstrates common ancestry between species.
Members of the same species will be expected to?
Members of the same species can breed and produce viable offspring that will, when mated with others of the same species, also produce viable offspring.
