What is temporal isolation and how does it contribute to the process of speciation in biology?
Temporal isolation is a type of reproductive isolation where species reproduce at different times, such as different seasons or times of day. This prevents them from mating and producing offspring together, leading to the formation of new species over time through the process of speciation.

What is gradual speciation speciation?
The gradual model of speciation holds that species originate by slight morphological changes over long time spans. For example, sedimentary rock layers ofen hold veritical sequences of fossilized shelles of foraminiferans. The sequnce reflects graduatal morphological change. (From my Biology 101 book: 'Biology: The Unity and Diversity of Life').
What is instantaneous speciation?
Instantaneous speciation is a hypothetical concept that suggests a species can suddenly split into two separate species without any transitional forms. This is not widely accepted in mainstream evolutionary biology, as speciation is generally considered to occur over longer periods of time through various mechanisms such as natural selection, genetic drift, and geographic isolation.
What is gametic incompatibility?
Gametic incompatibility is the inability for a sperm to penetrate and fertilise the egg. For example, in abalones, the sperm carries a lysin protein that dissolves a hole in the egg's envelope, but only in eggs from the same species of abalone (D.J. Futuyma, Evolutionary Biology, 1998)
What is an instantaneous speciation?
Instantaneous speciation, also known as saltation, is a theory in evolutionary biology that suggests new species can arise suddenly and rapidly, rather than through gradual accumulation of small changes. This idea challenges the traditional view of gradualism where species evolve slowly over time. However, there is limited empirical evidence to support the concept of instantaneous speciation.
What are some non examples of community biology?
Mathematics, computer science, and physics are examples of fields that are not considered community biology. Additionally, studying individual organisms in isolation, without considering their interactions within a community, would also be a non-example of community biology.
Who is Ernst Mayr?
Ernst Mayr was a German-American biologist known for his work in evolutionary biology and ornithology. He proposed the Biological Species Concept that defines species based on reproductive isolation. Mayr's research contributed significantly to our understanding of speciation and the role of geography and isolation in evolution.

What does specialization mean in?
Speciation in Biology means the growing of new species.

What are the three types of isolating mechanisms?
The word isolate has its origin in Latin where it is concerned with an island. In Physics one could isolate a region from an incoming wave, such as light, heat, sound, vibration, X-rays and so on. In Chemistry one could isolate a substance on the basis of its optical refraction, or where it was on the acid-base scale. In Biology one could isolate one species or sex from the remainder. There are more, but the general meaning is to separate.
How does allopatric speciation occur?
Allopatric speciation: ( other country ) A speciation event that is facilitated geographically. A population is split along geographic lines, mountains, rivers, and the now separate gene pools vary in allele frequency over time enough to , possibly, have two new species arise. Sympatric speciation: ( same country ) An in place speciation event where a sub-population within a population begins to vary their alleles from the main population. Perhaps a slight temporal, or water level difference, or mating differences can facilitate this. This speciation event is still a matter of contreversy in biology. Simplified explanations.
When two species become so different that they can no longer breed it is called what?
On my worksheet for biology the possible answers for that exact question areinfertilityextinctionisolationselection.hope that narrows it down_____________________________The answer is: isolation.
What is a conspeciation?
Conspeciation is a process in evolutionary biology where two or more populations of organisms diverge and evolve into separate species while remaining in the same geographical area. This occurs due to reproductive isolation mechanisms, such as behavioral differences or ecological specialization, that prevent interbreeding. As a result, these populations can adapt to different niches or environments, leading to speciation without geographical separation. This contrasts with allopatric speciation, where populations are physically separated.
List and describe the different types of genetic isolation?
geographic isolation- the physical separation of members of a population reproductive isolation- the inability of members of a population to successfully interbreed with members of another population of the same or related species information from MODERN BIOLOGY by HOLT, Rinehart and Winston

How is the different finch species in the Galapagos an example of geographic isolation?
The different finch species in the Galapagos have evolved through geographic isolation on different islands. Each island has its own unique environment and food sources, leading to variations in beak shape and size among the finches to adapt to their specific diets. This is an example of how geographic isolation can drive speciation and the development of unique traits in isolated populations.
