The ancestors of tigers didn't have stripes. Use the theory of natural selection to explain how tigers may have evolved to have stripes.?

It may be those with stripes were more successful hunters. Many people think a large orange-coloured cat with black or brown stripes is going to stand out in the green of forests. However, research has clearly demonstrated that with the dappling effect on light found in forests, tigers blend in very well. Therefore, a striped cat would be a more successful hunter. A more successful hunter feeds well and is in better health. That makes it more attractive to a mate, it reproduces more and leaves behind more offspring. Consequently, striped cats become more common.

How do you know the ancestors of tigers didn't have stripes? It's more likely they had some striping that has become more pronounced in the tiger and lost in the lion. In the tiger's environment stripes have a camouflage advantage allowing those with stripes to have better success at surviving and reproducing, leading to an increase in this trait by loss of other alleles. Conversely the lion is better adapted by having a plain coat and so it adapts by losing the alleles that produce stripes.

The tiger ancestors that develop stripes had better camouflage so they out performed their rivals so they became the dominant species of the area

Habitat differences.

Mutations caused some tigers to have stripes. This helped camouflage them from prey, making them better hunters, and better survivers. This would have allowed those with stripes to mate and reproduce more than those without stripes, passing on the mutated gene for stripes to their descendants.

im really surprised...not one dumbass answer of evolution is not real...way to yahoo people

What everyone else said. Stripes evolved independently in lots of different lineages, as camouflaging against predator vision or prey vision. The ones with stripes reproduced more than the ones without. ... of course, then I would have to wonder why extant lions aren't spotted in adulthood, wouldn't I. ... and I would have to wonder how lions made it to North America and tigers didn't.

If you see tigers in the long grass of the savanna the stripes and colouring are excellent camouflage, useful for hunter or prey alike. It is possible that some tiger ancestors developed stripes before they became tigers. Stripes are quite a common feature of animal fur. In fact humans have stripy skin in the UV range - some more than others tho.

They are thought to have got stripes in the manner described by the Morphogen Theory which you can look up. In the context of Evolution via Natural Selection, the more the stripes began to work as effective camoflague in the jungle or forest, the more likely that tiger would have been to feed well and have offspring. So over thousands and thousands of years tigers that had stripes became the bulk of the population.and eventually became the norm.

The stripes make it easier for them to sneak up on their prey. So if a few had stripes, they ate better than the others, and could feed their cubs.
