Now consider there are two different rivers instead of one. If a boulder were to obstruct its flow into a crevice, it would take a turn around the crevice. (2017, November 05). Suppose both encounter a big enough boulder, and both the boulders are This is exactly what convergent evolution is all about. The boulder represents ‘natural selection’. However, convergent evolution was only a play of words that evolutionary biologists came up with to explain one of their many observations; it has got nothing to do with divergence as such.
Get in touch with us and we'll talk...The main point to be borne in mind here is that the ‘boulder’ has to be ‘Confusing? If however a big enoughboulder were to stand in between its path, the river would split into two and give rise to two new smaller rivers, each of which would meet its separate fates as it flowed down the mountain. If this were to happen, one of the two species would in fact be driven to extinction. However, the term ‘natural selection’ is now interchangeably used as cause and effect.One thing to be borne in mind however, is the fact that the ‘boulder’ has to be ‘Convergent evolution has nothing to do with divergent evolution.

On the other hand, penguins and ostriches are both flightless birds, both of which have evolved to walk on the ground.

While divergent evolution is the phenomenon in which two species have common ancestors, but develops different characteristics due to changes in the environment which they adapt slowly and hence gives rise to new species. Hence for ‘speciation’ (creation of a new species) to sustain, it is essential that evolution be gradual.

But in spite of both being birds, they have evolved very differently with respect to other features. We also use third-party cookies that help us analyze and understand how you use this website. For example, in vertebrates like pigs, birds, monkeys and whales, the forelimbs have the same general sets of bones, but they have been modified over time so the animals can use their forelimbs in very different ways. We'll assume you're ok with this, but you can opt-out if you wish. However, for the ease of understanding, I will first explain divergent evolution and then move onto convergent evolution.Imagine evolution of life to be a process like the flowing of a river.

What exactly is the difference between the two?Of the several confusions that persist in the field of evolutionary biology, one is that about convergent and divergent evolution. Of the several confusions that persist in the field of evolutionary biology, one is that about convergent and divergent evolution. Well, we're looking for good writers who want to spread the word. how related or unrelated are the two species we are talking about. The other term – Convergent Evolution – is often regarded as the opposite of Divergence. The classical examples of evolution, such as Darwin's finches, demonstrate the opposite process: divergent evolution. It is a totally different concept. Both the rivers encountered a ‘boulder’, hence they were both destined to similar fates – to split. Get in touch with us and we'll talk...Of the many concepts that were elaborated in this book (like survival of the fittest) one was Darwin’s Principle of Divergence. If however a This is exactly what divergent evolution is all about. But even with so many controversies, “Would you like to write for us? In divergent evolution, a single species interbreeds, either through natural means or artificially chosen traits and selective breeding, and then that species begins to branch off and become a different species.
rather than the actual pressure.
