Why are cats and dogs so similar?
Cats and dogs are similar in that if they were let loose in the wild, they would be able to fend for themselves. Once domesticated, things like shelter and protection are provided by their owners. Nevertheless, they retain their instincts and are able to use these similarly.
You may have thought that dogs would be a little closer to humans on the evolutionary scale, but it turns out that cats actually have 90.2\% of the DNA in common with us! You read that right! Cats are genetically surprisingly closer to us than dogs, who share about 84\% of the genes with us (Pontius et al, 2007).
Why do all animals of the same species look the same?
To the untrained eye , individual wild animals of even a same species look similar because they have a limited distribution over an area with similar climatic and geographic conditions and hence they respond to the environmental factors in a similar manner .
Why do dogs of the same breed look the same?
These animals are often genetically very closely related, or at the very least, mating was done between two animals that already look very similar. As a result, these show-quality purebreds are about as hard to tell apart as human siblings—or even as hard as identical twin humans.
What is a cryptic animal?
Cryptic species – animals that appear identical but are genetically quite distinct – may be much more widespread than previously thought. The findings could have major implications in areas ranging from biodiversity estimates and wildlife management, to our understanding of infectious diseases and evolution.
Why do organisms don’t look the same?
Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment.
Are cats of the same species as dogs?
All domesticated cats are of the same species, as are dogs. As it has already been pointed out, cats have much less dimorphism than dogs simply because of humans. We don’t have a reason to breed them in different sizes as they are not working animals.
Why do cats look so different from dogs?
Just cause they’re similar in size (much smaller range than dogs in terms of size) don’t mean they don’t look different. Cats have different tail shapes and sizes, different eye colors, pupil shapes, hair colors, patterning, and spotting across the fur.
Why do animals look different from one another?
Unexpected variations in the looks of an animal that’s been bred — unusual size, lack of a tail, curly hair or peculiar markings, for example — are the result of genetic mutations, which appear naturally “all the time,” and are then perpetuated through generations by people who find the new trait appealing, according to Lyons.
Why do people breed multiple dogs to get different traits?
People identify a genetic trait that they wanted their dog to have, and breed two dogs with that trait, hoping for the offspring to have that trait. Then they’d breed that offspring with another dog with that trait, again hoping for the same thing. Over time, that trait becomes more and more exaggerated.
