Not neccessarily - it depends on how far they have mutated/evolved. Don't forget that classification/nomenclature are constructs designed to make man's life easier - where any division (sub-species, species, genus, family etc etc.), starts and ends is purely an arbitrary decision on the part of taxonomists.
Yes, a lion is called felis concolor, and a house cat is called felis domsticus. When the first word, otherwise known as the genus, is the same, it means they are related in some way.
Same genus or closely related species.
Two organisms that are related will share the same genus name in their scientific name.
You can tell how closely related organisms are by determining the lowest classification that they share. For example, organisms that share the same genus will be more closely related than organisms that share the same family.
Two organisms belonging to the same genus always belong to the same family.
A group of closely related species would share the same genus.
if 2 or more organisms have more than one of the following the same, they are closley related: kingdom, phylum, class,order,family,genus,and species
Order is as follows: Life Domain Kingdom Phylum Class Order Family Genus Species To answer your question, animals in the same Genus are more closely related then those of the same Order.
no
Animals within the same genus are more distantly related.
why are members of the same genus more likely to compete for a niche than organisms than in different families
Not necessarily, there can be many similarities and differences within a genus
why are members of the same genus more likely to compete for a niche than organisms than in different families
