Бурокрылая птица-мышь Colius striatus | Bird species, Speckle, Species
Oct 28, 2022 - A geographically-variable, dumpy-bodied, brownish-gray bird with a long, scruffy tail. Differentiated from other mousebirds by its blackish face and gray-brown crest. It is often found scrambling through bushes and tangles, creeping around on short legs. In flight, it flutters rapidly, and its tail seems to drag it down, as if it were too heavy to make it to the next bush.

Species that have evolved to be near identical? Are there any species that are near identical in outward appearance but are separate species? When I say species I mean can’t interbreed.
Simple answer: yes, an uncounted number of them. You need to read up on two topics: convergent evolution and mimicry. Convergent evolution is when environmental factors cause different creatures to evolve similar appearance and lifestyle. Perhaps the classic example of this are the dolphins and icht...

What species is most prolific? What species represents the largest biomass on earth, ie, how much does the entire population weigh? Also, what species has the most members?
Briefly, the single species that weights the most is the **cow** (520 million tonnes in 2011, now probably way more). Collembola, however, are made up of ~6000 species. The same goes for ants and termites.

How does a new species survive without suffering inbreeding? Just what the title states. The thought came from reading When has an organism evolved enough to be called a new species? I'm probably wrong but I understa...
Usually what happens initially is geographic isolation of some members of a species, so in that sense the inbreeding is something that is influencing and is going to evolve, but eventually shapes this species to better cope adapt to some environment, or evolves the new species out of existence.
