Yes, speciation is an example of micro-evolution in organisms. It refers to the process by which distinct species evolve from a common ancestor through the accumulation of genetic differences over time. This gradual divergence can lead to the formation of new species that are reproductively isolated from one another.
Actually it is.
Speciation without geographic isolation is called sympatric speciation. This type of speciation occurs when new species evolve from a common ancestor in the same geographic area. It is often driven by other factors such as ecological or reproductive isolation.
Allopatric speciation occurs when a population of organisms is separated geographically, often by a physical barrier like a river or mountain range. Over time, the isolated populations may evolve different traits due to genetic drift, natural selection, or mutations. Eventually, they may become distinct species that can no longer interbreed successfully.
Both sympatric and allopatric speciation involve the formation of new species through the genetic isolation of populations. In both cases, reproductive barriers develop that prevent gene flow between populations, leading to divergence and eventually the formation of separate species. The key difference between the two is that sympatric speciation occurs within the same geographic area, while allopatric speciation involves speciation due to geographic isolation.
Speciation in Biology means the growing of new species.
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').
The two factors that affect speciation are isolation, which can be geographic or reproductive, and genetic divergence, where populations accumulate genetic differences that prevent interbreeding. These factors can lead to the formation of new species over time.
As part of the environment of other organisms humans can have great effects on speciation. Especially adaptive radiation. As we contribute heavily to the extinction of some species other species flow into those open niches and radiate outwards to possible 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.

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.
Allopatric speciation.
Technology and biology have a great relationship with each other. Advancements in technology tell you what in biology can be manipulated or studied for example.

human and social biology is the study of man and his surroundings and how they affect each other
