Mongoose (Herpestidae)
Similarities Among Species Shared Traits • Short legs • Long, skinny body. • Color variability among subspecies is usually connected with soil color for camouflage.
Common Ancestor is Feliformia
Environment
Sub-saharan Africa
Thick scrub or low forest Job
• Feed primarily on insects, small reptiles, and birds.
• Are eaten primarily by snakes, storks, and hawks.
SlenderMongoose (Galerella Sanguinea)
Fossil Record
Previously, the slender mongoose had smaller teeth, were smaller in body size, and had sharper claws.
Non-Shared Traits some of the smallest mongooses. finer, silkier fur …show more content…
II. Job climb trees to kill birds unlike most others
Non-Shared Adaptive Value In Environment of Species: climb trees to eat birds and move around in its habitat.
Speciation
Approximate time of speciation: 3.85-4.27 million years ago from Galerella Nigrata.
Theorized cause of speciation: The desert in Namibia expanded, causing the two species to be cut off.
Banded Mongoose (Mungos Mungo)
Fossil Record
The hypothesis is that as the climate changed and became drier, the Meerkat developed a higher propensity for survival in the southern tip of Africa and evolved into the banded mongoose.
Non-Shared Traits
All females can breed, whereas most other mongoose females cannot all breed. a series of black bands across the back, between the mid-back and the base of the tail
Differences between niche of species I. Environment •No significant differences II. Job • Helps Baboons and Warthogs
1-3 mongooses guard the females during estrus.
Non-Shared Adaptive Value In Environment of Species
Cheek teeth tend to have low, rounded cusps.
