CARLEY, Justice.
In an attempt to elude officers after committing a burglary, Graham and co-defendant Diamond engaged in a high-speed vehicular chase which did not end until their vehicle crashed into another. Three of the occupants of the vehicle into which they crashed were killed. One of the occupants was nine-months pregnant and her unborn child did not survive the crash. As the result of these events, a multi-count indictment was returned against Graham and Diamond. The trial court denied Graham's motion to sever his trial from Diamond's. At a jury trial, Graham was found guilty of three counts of felony murder for which he was given three life sentences. He was also found guilty and sentenced for the following offenses: feticide; theft by taking; possession of a firearm by a convicted felon; possession of a firearm during the commission of a crime; violation of the Georgia Controlled Substances Act; giving a false name; and, fleeing from police officers. He appeals from the judgments of conviction and sentences entered by the trial court on the jury's guilty verdicts.[1]
1. Construing the evidence most strongly for the State and against Graham, it was sufficient to authorize a rational trier of fact to find proof of his guilt of the numerous offenses beyond a reasonable doubt. Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979).
2. Graham urges that it was error to fail to give an unrequested charge that the *365 conviction of one of the co-defendants did not require the conviction of the other. However, the record shows that Graham affirmatively waived his right to predicate an enumeration of error upon the trial court's charge. White v. State, 243 Ga. 250, 253 S.E.2d 694 (1979). Moreover, even if the right to enumerate error as to the trial court's charge had not been waived, the record shows that the charge, as given, was sufficient to apprise the jury that the guilt of Graham and Diamond should be determined separately. Nicholson v. State, 265 Ga. 711, 713(3), 462 S.E.2d 144 (1995).
3. Graham correctly asserts that he cannot be sentenced for the underlying felonies as well as for the felony murders, since the former merged into the latter. Zackery v. State, 257 Ga. 442, 443(2), 360 S.E.2d 269 (1987). However, the record clearly shows that Graham was sentenced only for the felony murders themselves and not for the burglary which underlay them.
Graham further contends that it was error to impose a separate sentence for each of the other offenses. All of the offenses for which Graham was given a separate sentence may have been part of a continuous crime spree, but each one was a separate and distinct offense from any of the others. Butler v. State, 239 Ga. 591, 592(3), 238 S.E.2d 387 (1977); Kramer v. Hopper, 234 Ga. 395, 396-397, 216 S.E.2d 119 (1975). Compare Hubbard v. State, 168 Ga.App. 778, 779(2), 310 S.E.2d 556 (1983) (single theft of multiple articles). Accordingly, imposition of a separate sentence for each of the offenses was authorized.
4. Graham urges that his sentences constitute cruel and unusual punishment since Diamond was the driver of the vehicle. However, Graham's guilt for all of the offenses was sufficiently established under the relevant "parties to a crime" principles of OCGA § 16-2-20 and his sentences are within the statutory limits. "[L]egislative enactments constitute the clearest and most objective evidence of how contemporary society views a particular punishment. [Cit.]" Fleming v. Zant, 259 Ga. 687, 689(3), 386 S.E.2d 339 (1989). "[L]egislative discretion must be deferred to unless, under the circumstances, the sentence shocks the conscience. [Cits.]" Lambeth v. State, 257 Ga. 15, 16, 354 S.E.2d 144 (1987). The sentences imposed against Graham for the crimes to which he was a party do not shock the conscience and his "contention that his sentence[s are] excessive may be presented to the sentence review board as provided in [OCGA § 17-10-6]." Mydell v. State, 238 Ga. 450(2), 233 S.E.2d 199 (1977).
5. Graham enumerates as error the denial of his motion to sever his trial from Diamond's. The trial court's discretionary ruling in this regard will not be disturbed unless there is a clear showing of prejudice. Adams v. State, 264 Ga. 71, 73(3), 440 S.E.2d 639 (1994). Absent a showing of harm, the mere existence of "purported antagonistic defenses between two co-indictees is not sufficient to warrant the grant of a separate trial...." Chapman v. State, 263 Ga. 393, 394(2), 435 S.E.2d 202 (1993). Where, as here, the co-defendant takes the stand and is subject to cross-examination, no prejudice is shown. Durham v. State, 240 Ga. 203(1), 240 S.E.2d 14 (1977).
Judgments affirmed.
